Blue Lagoon Iceland Guide: Is It Worth It, and How to Visit

The Blue Lagoon is Iceland’s most famous geothermal spa, and for a lot of visitors it’s the first or last thing they do in the country. We’ve been several times over the years, in both winter and summer, and at different times of day, so we’ve soaked here on a freezing dark morning and under the low sun late on a summer evening. This guide pulls together everything we’ve learned across those visits, along with the questions we get most often from readers, to help you decide whether the Blue Lagoon is right for your trip and, if it is, how to do it well.

The Blue Lagoon isn’t for everyone. It’s expensive, it can be busy, and Iceland has hundreds of cheaper (and, some would argue, nicer) thermal pools. But it’s also a one-of-a-kind place (National Geographic once named it one of its 25 Wonders of the World), and every time we’ve gone we’ve come away glad we did. Below we cover whether it’s worth it, how it compares to the Sky Lagoon, the current volcanic and safety situation, what everything costs, and exactly what to expect on the day.

Quick take: the Blue Lagoon is worth it if this is your first trip to Iceland, you want the iconic milky-blue soak, or you’re passing Keflavík Airport with a few hours to spare. It’s easy to reach, welcomes children from age 2, and the facilities are excellent. Skip it (or pick a cheaper thermal pool) if you’re traveling on a tight budget or you’re hoping for a quiet, uncrowded dip. Deciding between it and the Sky Lagoon? Choose the Blue Lagoon for the famous scenery, an airport stopover, or a visit with young kids, and the Sky Lagoon if you’re based in Reykjavík and want ocean views (much more on that below). As of July 2026 the Blue Lagoon is open and operating normally, though the nearby volcanic system is still active, so it’s worth checking the status before you go.

 

Is the Blue Lagoon Worth It? Our Verdict

Yes, we think the Blue Lagoon is worth visiting, as long as you go in with the right expectations. It’s a unique and beautiful place, and we’ve enjoyed every visit. But it’s also an expensive, developed resort that gets up to 4,000 visitors a day and sits right next to a geothermal power plant. If you’re picturing an empty milky-blue pool in the middle of nowhere, you’ll be disappointed. If you’re picturing a well-run, scenic spa where you can soak for a couple of hours with a drink and a mud mask, that’s exactly what you get.

Blue Lagoon at a glance
Location	Grindavík, Reykjanes Peninsula (about 20 minutes from Keflavík Airport, 45 to 50 minutes from Reykjavík)
Entry from	ISK 11,990 (Comfort Package, dynamic pricing)
Water temperature	37°C to 40°C (98°F to 104°F), year-round
Time to allow	At least 2 hours
Minimum age	2 (free for ages 2 to 13)
Booking	Advance booking required, often sells out
Status (July 2026)	Open, but in an active volcanic zone, so check before you go

Who should skip it: if budget is a real concern, we’d steer you toward one of Iceland’s many cheaper geothermal pools instead (see our alternatives section below). The same goes if crowds put you off, or if you’re only after somewhere to swim laps, this is a place to float and relax, not to swim.

Who will love it: first-time visitors to Iceland, families with young children (the age minimum is just 2, versus 12 at the Sky Lagoon), anyone with a few hours to fill near the airport, and travelers who want that famous bucket-list soak. If any of those describe you, book it.

One practical tip that makes the difference between “worth it” and “overpriced”: give yourself time. The people who tell us they felt short-changed were usually the ones who rushed through in an hour. Book the entry-level Comfort Package (it includes everything you actually need, towel included), set aside at least two hours, and you’ll get your money’s worth.

 

Blue Lagoon vs Sky Lagoon: Which Should You Choose?

Readers ask us which of these two to choose more than almost anything else about Iceland. The Blue Lagoon and the Sky Lagoon are Iceland’s two big-name geothermal spas, and most visitors to Reykjavík end up picking one or the other. We’ve visited the Blue Lagoon many times. We haven’t been to the Sky Lagoon ourselves, but it gets consistently strong reviews, and the practical differences between the two are clear enough to make a confident recommendation either way.

Here’s how they stack up:

Feature	Blue Lagoon	Sky Lagoon
Opened	1987 (to the public)	2021
Location	Grindavík, Reykjanes Peninsula. About 20 minutes from Keflavík Airport, 45 to 50 minutes from Reykjavík	Kópavogur, about 6 km (10 to 15 minutes) from central Reykjavík, but further from the airport
Entry from	ISK 11,990 (Comfort Package)	ISK 12,990 (Saman Pass)
The setting	Silica-rich milky-blue water set in black lava fields, mud masks, swim-up bar, steam cave	Infinity-edge pool overlooking the North Atlantic, with a 7-step Skjól bathing ritual
Size and crowds	Large, absorbs big numbers well but is the busier of the two	Smaller and more intimate
Minimum age	2 (families welcome)	12
In the volcanic zone?	Yes, closes briefly at the start of an eruption	No, outside the affected area
Best for	First-timers, families, airport stopovers, the famous scenery	Reykjavík-based travelers, adults, ocean views, the ritual experience

Our recommendation. If it’s your first trip to Iceland, if you’re traveling with young children, or if you want to visit on your way to or from the airport, choose the Blue Lagoon. It’s the more famous of the two, the scenery is remarkable, and it’s the easy, family-friendly option. If you’re staying in Reykjavík, don’t need to entertain kids under 12, and like the sound of an ocean-view infinity pool and a structured bathing ritual, the Sky Lagoon makes more sense (and it’s closer to the city). One more point in the Sky Lagoon’s favor: it sits outside the volcanic zone, so it’s a reliable backup if the Blue Lagoon closes during your trip.

Note that the Sky Lagoon is now slightly more expensive than the Blue Lagoon at the entry level, so this isn’t a budget-versus-luxury choice. It comes down to location, the type of experience you want, and whether you have children under 12 in your group.

If you’d like to book Sky Lagoon admission, you can check current prices and availability for the Sky Lagoon here (this is the admission-only Saman Pass). If you’d rather include hotel pickup and drop-off, there’s also a Sky Lagoon admission with transfer option.

 

Is the Blue Lagoon Open Right Now? Volcanic Activity and Safety

If you’ve been reading the news about Iceland, you may be worried about the volcanic activity near the Blue Lagoon. Here’s the current situation, and our read on whether it should change your plans.

The Reykjanes Peninsula, where the Blue Lagoon sits, has been volcanically active since late 2023. There were nine eruptions along the Sundhnúkur crater row between December 2023 and August 2025, near the town of Grindavík and close to the Blue Lagoon. During several of these the Blue Lagoon closed as a precaution and was evacuated, and each time it reopened once the authorities judged the area safe, usually within hours or days. The spa has since built protective lava barriers around its infrastructure and has well-rehearsed evacuation procedures.

As of July 2026, there is no active eruption, and the Blue Lagoon is open and operating normally. The most recent eruption ended in early August 2025, and the pause since then is the longest in the current series. Still, scientists at the Icelandic Meteorological Office continue to monitor magma building up beneath the nearby Svartsengi area, and another eruption is considered more likely than not at some point. The alert level for the area is currently “heightened,” and warning times before an eruption can be short, sometimes only 20 minutes to a few hours. In practice, this means there’s a small chance the Blue Lagoon could close at short notice during your visit.

Our advice is not to let this put you off. The eruptions so far have been localised and haven’t affected flights, Reykjavík, or the wider tourism infrastructure, and millions of people have continued to visit the Blue Lagoon throughout this period. But we’d take a few sensible precautions:

• Check the Blue Lagoon’s seismic activity page when you book, and again a day or two before your visit.
• Book through a platform with free cancellation, such as Tiqets or GetYourGuide. This gives you flexibility if there’s a last-minute closure.
• Keep an eye on SafeTravel.is and the Icelandic Meteorological Office for the latest alerts.
• Have a backup plan. If the Blue Lagoon closes during your trip, the Sky Lagoon near Reykjavík is a good alternative and sits outside the volcanic zone.

If the Blue Lagoon is closed when you have a booking, you’ll receive a full refund. Several of our readers have had to reschedule or switch to the Sky Lagoon during eruptions, and in each case the process was simple.

 

How Much Does the Blue Lagoon Cost?

The Blue Lagoon uses dynamic pricing, which means the cost of your visit depends on the date, the time of day, and which package you choose. Prices are generally lowest for early-morning and late-evening slots, on weekdays, and outside the peak summer season (June through August). Because prices move around, treat the figures below as starting points rather than fixed rates.

There are four entrance packages. All of them include unlimited time in the lagoon, plus access to the sauna, steam room, steam cave, and relaxation areas.

Package	From (ISK)	What’s included
Comfort	from 11,990	Entry to the pools, a silica mud mask, one drink from the swim-up bar, a towel, and use of a locker
Premium	from 14,990	Everything in Comfort, plus a bathrobe, a second drink, and two extra face masks of your choice at the Mask Bar (algae, mineral, or lava)
Signature	from 18,490	Everything in Premium, plus take-home skincare (a 30 ml Silica Mud Mask and a 30 ml Mineral Mask). A seasonal offering that isn’t always available
Retreat Spa	from 89,000 per changing room (for two guests)	A separate luxury experience with private changing rooms, the Retreat Lagoon, the Blue Lagoon Ritual, and access to the main lagoon. Minimum age 12

Our pick of the four is the Premium Package. If you plan to spend a couple of hours or more here, the bathrobe makes a real difference moving between the lagoon, sauna, and steam cave, particularly in winter, and the extra masks are a nice touch. Even so, the Comfort Package includes everything you need to enjoy the lagoon, so if you’re watching the budget, book Comfort and don’t feel you’re missing out. The Signature only makes sense if you were already planning to buy Blue Lagoon skincare, since the take-home products are worth more than the price difference.

A couple more things to note. The Blue Lagoon no longer includes slippers with the Premium admission, as part of its sustainability program, though you can rent them on-site for around ISK 1,500. And because of the dynamic pricing, the only way to see the exact cost for your dates is to check the Blue Lagoon website directly. You can also compare prices on GetYourGuide, which sometimes offers fixed pricing without the dynamic fluctuations, plus free cancellation.

Children aged 2 to 13 can visit for free with a paying adult. Children under 2 aren’t permitted into the swimming area, as the mineral content can be harmful to very young skin, and children aged 2 to 8 must wear arm floats (provided free on-site). Each adult can supervise a maximum of two children.

For a bit of perspective on how much prices have climbed: when we first visited back around 2018, the Comfort Package was about ISK 6,900. Costs have risen a lot since then, but so have the facilities. The Blue Lagoon added two new waterfalls, a cold plunge pool, and various upgrades across 2024 and 2025.

 

How to Get to the Blue Lagoon

The Blue Lagoon is inside the Reykjanes UNESCO Geopark, about 13 miles (20 minutes’ drive) from Keflavík Airport or 30 miles (45 to 50 minutes’ drive) from central Reykjavík. The full address is Blue Lagoon, Norðurljósavegur 9, 240 Grindavík (GPS 63.8804° N, 22.4495° W).

Because of where it sits, the most popular times to visit are on the way to or from the airport, as a day trip from Reykjavík, or as part of a Golden Circle tour. If you’re driving, there’s free parking in front of the reception area.

 

Blue Lagoon from Keflavík Airport

Visiting on your way to or from Keflavík is one of the easiest options, since it’s only about a 20-minute drive. You can rent a car and drive yourself, or take a shuttle or taxi.

It’s easy to rent a car at the airport, and we recommend looking at the rental cars available online here, a service that focuses specifically on car rental in Iceland and lets you add the local insurances (like sand-and-ash protection). If you’re renting, note that Iceland introduced a kilometer-based road tax in January 2026 (ISK 6.95 per km), which rental companies add automatically to your final bill. Fuel prices dropped as a result, to around ISK 185 to 230 per liter.

If you’d prefer a shuttle from Keflavík Airport, you can book the official shuttle here. The same operator runs journeys back to the airport or on to Reykjavík.

 

Blue Lagoon from Reykjavík

Visiting as a trip from Reykjavík is the other popular option, about a 45 to 50 minute drive from the city center.

For a shuttle from Reykjavík, you can book a return transfer here, or use the official shuttle. The bus picks up and drops off at most hotels and guesthouses in Reykjavík, or at the nearest bus stop. If you’re traveling as a small group, a private transfer can be just as cost-effective and more convenient.

 

Blue Lagoon as Part of a Day Tour

Plenty of guided day tours from Reykjavík include a stop at the Blue Lagoon, especially those built around the Golden Circle. Note that most tours don’t include your lagoon reservation or entrance fee, so check this and book your entry time to line up with the tour. A good tour will help you coordinate the timing.

Some day tours to consider:

• This full-day tour covers the Golden Circle highlights (Thingvellir National Park, Kerið Crater, and Gullfoss waterfall) and ends at the Blue Lagoon.
• This small-group tour also combines the Golden Circle highlights with a Blue Lagoon visit.
• This full-day tour adds the Kerið volcanic crater to the Golden Circle route before finishing at the Blue Lagoon.
• This private tour gives you a private guide for the Golden Circle and the Fridheimar tomato greenhouse, followed by premium entry into the Blue Lagoon.

 

Do You Need to Book the Blue Lagoon in Advance?

Yes, advance booking is mandatory. The Blue Lagoon uses a timed-entry system and caps the number of guests each day, and slots regularly sell out days or even weeks ahead, especially in summer and around holidays. Walk-ins are rarely possible, and you can be turned away without a reservation.

You can book directly on the Blue Lagoon website, or through GetYourGuide for the Comfort or Premium package (subject to availability).

The two booking routes differ on cancellation. If you book directly, the Blue Lagoon requires you to cancel more than 24 hours ahead for a full refund, with no refund inside 24 hours. If you want more flexibility, we recommend booking through Tiqets or GetYourGuide, which both offer free cancellation. That flexibility is especially useful given the small chance of a volcanic closure (see our volcanic activity and safety section above).

The Blue Lagoon does allow an hour of flexibility on your arrival time for Comfort, Premium, and Signature bookings, though arriving later than that isn’t guaranteed. If you need to change an existing booking, contact the Blue Lagoon before your visit date.

 

What to Bring to the Blue Lagoon

The only things you really need are proof of your reservation and a swimsuit. But here’s what we’d pack to make the visit easier:

• Swimsuit or trunks
• A waterproof case for your phone or action camera, if you plan to take photos in the water
• A comb or brush and any hair essentials, plus a hair tie if you have longer hair
• Deodorant, facial moisturizer, and any other toiletries for afterwards
• Sandals, water shoes, or shower shoes
• A breathable waterproof bag for your wet swimsuit and other damp items afterwards
• A change of clothes, if you’d like something fresh after your shower
• Sunscreen (SPF 30 or higher) and sunglasses. Iceland’s sun can be surprisingly strong off the water
• A swim cap and a clarifying shampoo, if you’re worried about the minerals affecting your hair (more on hair below)

We’d keep all of this in a separate bag from the rest of your luggage, so you can easily take just those items into the spa. We also leave our jackets and coats in the car to avoid having to store them inside.

One more thing we’d sort before you fly: an eSIM for your phone. Having mobile data from the moment you land makes it much easier to find your way around, pull up your Blue Lagoon booking, and stay connected. We use and recommend Airalo, which has affordable Iceland data plans you can set up before you leave home. You can read our full Airalo review here.

A few notes on what you don’t need to bring. The Blue Lagoon provides complimentary shower gel and shampoo in the shower area, plus body lotion in the changing rooms, so you can leave your own behind if you’re happy using theirs. A towel is included with every package, so there’s no need to pack one (and if you bring your own, you’ll only end up carrying it around wet). And if you want a robe, it’s easier to book a package that includes one than to pack a bulky bathrobe. You can, in theory, turn up with nothing but a booking and rent or buy everything on-site, from swimwear to slippers, but it’s expensive, so bring your essentials with you.

Finally, most suitcases and larger bags won’t fit in the lockers or be allowed into the lagoon. There’s paid luggage storage at the Blue Lagoon if you need it (handy if you’re visiting on the way to or from the airport), which you sort before you check in.

 

What to Expect Inside the Blue Lagoon

The main event is simply soaking in the warm, milky water and taking in the strange, beautiful surroundings. Stand under one of the waterfalls and let the hot water pound your shoulders, coat your face in silica mud at the Mask Bar, take shelter in the steam cave, and pick up your complimentary drink from the swim-up bar. There’s a newer cold plunge pool if you want to alternate hot and cold, and an in-water massage available for an extra fee.

Out of the water, you can use the sauna and steam room, and there’s a relaxation area with chairs where you can rest and look out over the lagoon. Space in these indoor areas is limited, so you may need to wait your turn if it’s busy. There’s also a full-service spa, restaurants, a snack bar, and a gift shop on-site.

The lagoon covers a large area and handles the daily numbers surprisingly well. People tend to cluster around the entrance, the Mask Bar, the bar, and the waterfalls, so if it feels crowded, drift toward the edges and you’ll usually find a quieter spot.

 

Changing Rooms, Showers, and Icelandic Spa Etiquette

The changing areas are divided by sex, with separate rooms for men and women, each a set of large open rooms filled with lockers and benches, plus mirrors and hair dryers. You use your electronic wristband to lock and unlock your locker (remember the number).

Beyond the lockers you reach the showers, and this is where the most important rule comes in: you must shower naked, with soap, before putting on your swimsuit and entering the lagoon. Icelanders take pool hygiene seriously, and you’re asked to wash thoroughly, particularly your hair, face, underarms, groin, and feet. Soap, shampoo, and shower gel are provided.

If you’re shy about being naked in public, don’t worry, you have options. There are a handful of modesty changing stalls, and a good number of showers with curtains or screens (there used to be very few, but they’ve added more over the years). Changing in the open area is quicker, but you can visit without stripping off in public if you’d rather not. Booking a package with a bathrobe (or bringing your own) can help you feel more covered moving between the locker room, showers, and pool. And if privacy really matters to you, the Retreat Spa package includes a private changing room and shower.

One quirk we didn’t expect: unlike most public pools in Iceland, the Blue Lagoon doesn’t have the wall-mounted swimsuit spin-driers you’ll find elsewhere. We were surprised by this and asked why, and were told it’s because the silica in the water can ruin both the driers and the swimsuit fabric. So rinse your swimsuit in the shower, wring it out well, and store it in one of the free plastic bags provided (or your own wet bag). Give it a good rinse, since dried-on silica can wreck the material.

 

Towels, Robes, and How Long You Can Stay

A towel is included with every admission, for use during your visit and returned before you leave. Premium and Retreat packages also include a bathrobe. You’re welcome to bring your own towel or robe, but we’d just use the free towel rather than carry a wet one around for the rest of the day.

There’s no time limit once you’re in. You can stay from your entry time until closing, and most people spend two to four hours here, often breaking for a drink or a meal. We’d allow at least two hours to really enjoy the pools, remembering that some of your time goes on checking in, changing, showering, and drying off. Add more if you plan to eat or need to collect stored luggage.

 

Photography in the Blue Lagoon

You’re allowed to take photos and videos in the main outdoor lagoon area, but not in the changing and shower rooms, the sauna, the Retreat Spa, or the other spa sections.

Lots of people bring a smartphone or a waterproof action camera into the water. If you’re taking your phone in, a waterproof phone case is worth it, these are inexpensive and protect against the steam and water. We wouldn’t bring a regular camera into the lagoon at all unless it’s in a waterproof housing, as the steam alone can damage it. If you’re not planning to take photos, the easiest thing is to leave your phone and camera in the car, in your locker, or in luggage storage.

 

Spa Treatments, the Clinic, and Accessibility

Beyond the standard soak, the Blue Lagoon offers extra spa services for an additional fee, including an in-water massage (from around ISK 20,000 for 30 minutes), private massages, and beauty treatments using silica and algae. For more of these, the Retreat Spa package includes access to additional treatment rooms and facilities.

The Blue Lagoon’s original claim to fame was as a treatment for psoriasis. In the early 1980s, a few bathers with the condition reported their symptoms improved, clinical studies in the 1990s supported the benefit, and a dedicated clinic was established. Today, people with psoriasis can use the regular lagoon or book specialized treatments at the clinic, which may be covered by insurance for some visitors.

The complex is wheelchair accessible, with disabled parking, and the lagoon itself can be entered using specially designed wheelchairs provided on request. Guests who need assistance can bring a companion free of charge. If you have specific accessibility questions, it’s worth calling the Blue Lagoon before you book.

 

Our Experience at the Blue Lagoon in Iceland

Laurence and I didn’t quite know what to expect when we visited the Blue Lagoon for the first time. Our visit was in the morning around opening time in winter. We had our reservations booked and the check-in line was short. We did the Comfort Package, which included the towel, one free drink, and the silica mud mask.

We went our separate ways to the changing areas (one for men, one for women). There were plenty of free lockers and showers, and the electronic wristbands were easy to use. There was free shower gel, shampoo, and conditioner in the showers.

It was a bit confusing to work out how to get to the pool (you go through the shower room), but I think they’ve improved the signage since then.

The weather was freezing when we visited, so we both quickly dropped our towels and sandals on the racks and raced into the hot water. It felt wonderful, especially on such a cold morning. The bottom is soft on your toes, thick with silica and minerals.

A word on those towel racks: while there are numbers on the hooks, people throw and pile their stuff everywhere (especially when it’s busy), including on top of other people’s, so you may not get the same white towel back. We wouldn’t leave anything valuable here (wallet, keys, camera, phone, jewelry).

There are staff around the pool acting as lifeguards, drink servers, and security, and offering massages, so if you have a question you can find someone without going back inside. Many of them wear yellow safety vests.

Laurence and I floated around and explored the different areas of the spa. We spent a couple of hours in the pool, had fun with the silica mud masks, took a few bad selfies, and drank tasty blueberry smoothies. We checked out the steam cave, which is a pretty cool cave-like space, and had a look at the sauna and relaxation lounge. Mostly, though, we just enjoyed the warm water.

Laurence had his smartphone out for the first 15 minutes or so, then decided to return it to his locker rather than worry about holding it the whole time. Screens get steamy fast, so we’d definitely recommend a waterproof case or a waterproof action camera if you’re bringing any kind of camera.

We were among the first in that morning, but it did get busier by the time we left. The Blue Lagoon is large, though, and holds a lot of people. We found that visitors tend to gather in clumps (around the entrance, the mask area, the bar, and the waterfalls), and we could easily find quieter spots as we moved around.

We spent about two hours in the pool and it was hard to get out. If you go in winter, be prepared to never want to leave the warm water for the freezing air.

Then it was back to the showers and changing room. You drop your towel (and robe and slippers) in a designated bin before you leave, and your wristband is scanned on the way out. If you owe anything for drinks, food, or massages, you settle it there.

We had a snack in the café and a quick browse of the gift shop before heading off. Overall it was a fun, fairly hassle-free experience, and we both enjoyed it much more than we expected to.

The Blue Lagoon is expensive, that’s just a fact. Were we glad we visited? Yes, we were. But we wouldn’t recommend it to anyone traveling on a tight budget, because there are much better-value thermal spas in Iceland.

Would we go back? Well, we actually have, mostly because we’re travel writers and wanted to see how it compares in summer versus winter. If we were regular travelers, though, this would probably be a one-time visit, given how many other thermal pools, spas, and swimming pools Iceland has.

We’ve returned a couple of times since that first visit, to experience the Blue Lagoon in summer and at different times of day. You can see in the photos below how the color of the lagoon, the amount of steam, and the light all change depending on the season and the angle. (You can even spot the Svartsengi Power Station in the background of some of them, particularly the fourth one below, which you won’t often see in the Lagoon’s own brochure shots.)

Here are a few photos to give you a realistic idea of what it looks like:

 

The Blue Lagoon’s History and Water

For all its natural-looking appearance, the Blue Lagoon isn’t really a natural attraction. It’s fed by runoff from the neighboring Svartsengi geothermal power plant, which makes it a sort of quasi-natural creation, filled with a mix of seawater and freshwater of geothermal origin.

 

A Brief History

The lagoon came about almost by accident. The Svartsengi Power Station opened in 1976, the world’s first geothermal plant to generate electricity and provide hot water for district heating, and by 1977 pools of mineral-rich runoff had begun to form. It still heats thousands of homes across the Reykjanes Peninsula today.

In the early 1980s, a few local men with psoriasis, among them Valur Margeirsson and Gísli Kristjánsson, started bathing in the water and reported that it eased their symptoms. By the late 1980s it had become a popular bathing spot for people with skin conditions, and a clinic followed in 1994. The lagoon officially opened to the public for bathing in 1987, and the Blue Lagoon company was founded in 1992, later adding its own line of skincare products. By the mid-1990s it was drawing around 50,000 visitors a year, and a new bathing facility opened in 1999.

As tourism to Iceland boomed from 2010 onward, the Blue Lagoon’s numbers climbed with it, helped along by television coverage, travel-magazine features, and endless social-media photos. By 2017 it was welcoming close to 1.3 million visitors a year, and it still draws over a million annually, with up to 4,000 people a day at peak times. It remains the most visited paid attraction in Iceland.

 

Why the Water Is Blue

The name is a bit of a misnomer. The water itself is a milky white rather than blue, thanks to its high concentration (around 140 mg/kg) of silica. Silica reflects blue light more than other colors, so the sky reflecting off the water makes the lagoon glow blue. On overcast days it looks far less vivid, and depending on the mineral content and light it can even look more green than blue.

The lagoon holds roughly 9 million liters of geothermal seawater, naturally renewed about every two days. Alongside silica and salt, the water contains minerals including potassium, calcium, magnesium, sulfate, and algae, which is where its reputation for skin benefits comes from. The water stays between 37°C and 40°C (98°F to 104°F) year-round, so it always feels like slipping into a hot bath.

 

Food and Dining at the Blue Lagoon

There’s a range of places to eat on-site, from a quick snack to a Michelin-starred tasting menu.

The café near the entrance offers reasonably affordable snacks, sandwiches, drinks, and smoothies, with no reservation needed. The Lava Restaurant is a smarter option overlooking the lagoon, mostly à la carte, with occasional fixed-price two- and three-course meals and a dinner tasting menu (currently ISK 12,900). There’s a children’s menu, and you can dine in “relaxed casual” clothing, or even in your bathrobe over your swimwear during the day until 16:00. The Spa Restaurant serves an all-day à la carte menu for spa guests, most of whom eat in their robes.

At the top end, the Moss Restaurant is a Michelin-starred fine-dining experience serving a modern take on Icelandic cuisine, with five- and seven-course tasting menus. Reservations are essential and can be hard to come by in summer, and the dress code is smart casual.

Reservations are a good idea for the Lava and especially the Moss Restaurant. You can check current menus, prices, and book a table on the Blue Lagoon dining page.

 

Blue Lagoon Alternatives

If you’d like to soak in a geothermal bath in Iceland, the Blue Lagoon is far from your only option. We’ve covered the Sky Lagoon in detail above, so here are the other alternatives we’d point you toward, most of them cheaper and quieter.

Our own favorite is Earth Lagoon (formerly known as Mývatn Nature Baths) in northern Iceland. It’s probably the closest experience to the Blue Lagoon, less expensive, and usually less crowded, though it only makes sense if your itinerary takes you up north.

Other good baths include Krauma Baths in western Iceland, the Secret Lagoon in Flúðir, and Laugarvatn Fontana near the Golden Circle. We’ve been to all of these and plenty more, so if you’d like advice on which to pick for your route, just leave us a comment.

Beyond the spas, Iceland has many free or donation-only natural hot springs and a huge number of low-priced public swimming pools that locals use. There are over a dozen public geothermal pools in Reykjavík alone, each a fraction of the price of the Blue Lagoon. For more on visiting Iceland affordably, including cheaper baths and pools, see our Iceland budget tips guide.

 

Where to Stay Near the Blue Lagoon

Most visitors stay in Reykjavík, but if you’d rather be closer to the Blue Lagoon or Keflavík Airport, here are some options we’d consider:

• Start Hostel Keflavik Airport. A well-reviewed budget choice near the airport, with dorm beds and private rooms, and breakfast from 03:30 (handy for early flights). About 10 minutes from the airport and 20 minutes from the Blue Lagoon.
• Geo Hotel Grindavik. A modern hotel about 6 km from the Blue Lagoon in the village of Grindavík. Important note: Grindavík has been significantly affected by the volcanic activity since late 2023 and has been evacuated multiple times. It’s currently accessible, but conditions can change at short notice, so check the situation before booking and have a backup plan.
• Northern Light Inn. The closest off-site hotel to the Blue Lagoon, with views of the geothermal plant and the lagoon’s steam, a free shuttle to the lagoon, an on-site restaurant and spa, and airport transfers. We stayed here on our last visit, and it’s only about a 3-minute drive to the Blue Lagoon.
• Keflavik Luxury Apartments. Fully equipped apartments near the airport and the Blue Lagoon, with kitchens, living rooms, and balconies. A good pick for families or anyone wanting more space, about 20 minutes from the lagoon.

If you’d like to stay right at the Blue Lagoon, there are two on-site hotels. The Silica Hotel has its own private lagoon and verandas overlooking the lava fields, and your rate includes premium admission to the Blue Lagoon plus unlimited access to the quieter, guests-only Silica Lagoon. Rooms start from around ISK 90,000 a night. The Retreat Hotel is a five-star hotel, holds a Michelin Key, and is home to the Michelin-starred Moss Restaurant, with access to the private Retreat Spa and Retreat Lagoon. All 60 suites open onto the moss fields or the lagoon, and rooms start from around ISK 220,000 a night, usually with a two-night minimum. If budget is no object, it’s an exceptional place to stay.

 

A Step-by-Step Guide to Visiting the Blue Lagoon

The Blue Lagoon is very visitor-friendly, even if you’ve never been to a public bath before. If you’d like to know exactly how a visit unfolds, here’s what to expect from start to finish:

1. Check your reservation time and arrive at that slot. You’ll need your confirmation, either printed or on your phone to scan.
2. Take in what you need and leave the rest in your car, tour bus, or the luggage storage facility. It helps to pack everything you’re bringing into the lagoon into one bag, since it all needs to fit in a fairly small locker.
3. At reception there are usually separate lines for individual reservations, tour groups, and (occasionally) walk-ins. Hopefully you’re in the reservations line.
4. Show your confirmation at the desk. Staff check you in, explain the process briefly, and give you an electronic wristband (your locker key, spa-area access, and payment method in one), a towel, and anything else in your package.
5. Head to the changing areas (separate for men and women). Use your wristband to lock and unlock your locker, and remember the number.
6. Get undressed and shower. Showering naked is required before entering the lagoon (as it is at all public pools in Iceland). Shower gel, shampoo, and conditioner are provided. Wash your whole body, including your hair, then put on your swimsuit.
7. Some of the minerals are harsh on hair, so apply plenty of conditioner and consider leaving some in for extra protection. If your hair is long, tie it up. If your hair is fragile, keep it out of the water entirely.
8. Exit through the shower area toward the lagoon entrance. Take everything you need (towel, robe, sandals, waterproof phone case). You don’t need money or cards in the pool, since you charge any purchases to your wristband.
9. There are racks for your towel, robe, and sandals. It can be hard to find the same towel or robe again, so note the rack number, and don’t leave anything valuable here.
10. Walk into the warm water and enjoy. Collect your free mud mask and your complimentary drink from the swim-up bar, and take as long as you like.
11. To buy an extra drink, snack, or treatment while you’re in the water, just use your wristband and settle up as you leave.
12. If you’d like, visit the steam room, sauna, and relaxation lounge. These are co-ed, so you’ll want to keep your swimsuit on, and space can be limited.
13. When you’re ready to leave, head back to the locker room and shower again, rinsing and reconditioning your hair thoroughly.
14. Rinse and wring out your swimsuit in the shower (the minerals are tough on fabric), then store it in a provided plastic bag or your own wet bag.
15. Dry off and get dressed. There are mirrors and hair dryers in the locker room. Clear out your locker before you leave.
16. On the way out, return anything you rented, scan your wristband to settle any charges, and drop the wristband in the bin. Then you’re free to head to the car park, café, restaurant, or gift shop.

This is, of course, subject to change, but it should give you a good sense of what to expect and how to be ready for your visit.

 

12 Tips for Making the Most of Your Visit

After several visits, we’ve learned that a good Blue Lagoon experience mostly comes from getting a few small things right: booking ahead, protecting your hair, and giving yourself enough time. Here are our 12 tips.

 

1. Make Your Reservations Ahead of Time

The Blue Lagoon is extremely popular and often sells out days or weeks in advance. As soon as you know your dates and preferred time, book your entry so you don’t miss out or end up waiting around for a slot.

 

2. Plan Your Transport in Advance

The Blue Lagoon is nowhere near central Reykjavík, so you need a plan to get there. You can rent a car and drive (free parking), take a shuttle (book the official one here), arrange a private taxi, or visit as part of a day tour like this one.

 

3. Make Restaurant Reservations Ahead of Time

It’s not essential, but if you want to eat at the Lava Restaurant, and especially the Moss Restaurant, book ahead. You can reserve online or by phone. No reservation is needed for the café.

 

4. Consider Visiting On Your Way To or From the Airport

The Blue Lagoon is just 20 minutes from Keflavík Airport, which makes it a great stop between Reykjavík and your flight. You can book shuttles to and from the airport or the city. Arriving in Iceland, the warm water is a lovely way to shake off a long flight, and it makes an equally nice send-off on your way out, just leave plenty of time to soak, dry off, and get to the airport.

 

5. Bring a Waterproof Case for Your Phone or Camera

You’ll probably want photos in and around the water, so protect your gear from the steam and mist. We’d take a smartphone or a waterproof action camera like a GoPro rather than a larger camera, and use a waterproof case for your phone. If you’re traveling as a couple, family, or group, consider bringing just one phone into the water and sharing the photos afterwards. The less you have to carry and worry about, the better.

 

6. You Can Rent Gear, But It’s Best to Bring Your Own

If you turn up unprepared, you can rent or buy almost everything at the Blue Lagoon, from swimsuits to shower caps, robes, sandals, and skincare. But prices are high, so it’s cheaper and more comfortable to pack what you need. Every package includes a towel, so there’s no need to bring one unless you’d prefer to.

 

7. Take Care of Your Hair

The most common complaint we hear is that the minerals do a number on your hair, leaving even the healthiest hair dry, matted, and unmanageable for a few days (and the effect is stronger on dyed or color-treated hair). The good news is that it isn’t permanent.

To protect your hair, rinse it and coat it liberally in conditioner before you go in, and don’t rinse the conditioner out. Put it up in a ponytail or bun and keep it out of the water where you can. The best protection, and what the staff recommend if you really want to keep your hair dry, is a swim cap (you can rent or buy one on-site). Afterwards, shower and wash your hair thoroughly, using a clarifying shampoo if your hair reacts badly to minerals, and condition again. A deep-conditioning treatment the next day helps too. And if your hair does come out a bit fried, don’t panic, it usually recovers within a week.

 

8. Remove Your Jewelry and Contact Lenses

Take off any jewelry, glasses, watches, and other valuables before going in. The geothermal water can damage some metals (we wear our wedding bands and nothing else), and the milky water hides a soft, shifting silica bottom where a dropped ring, earring, or contact lens is gone for good. The Blue Lagoon strongly recommends removing contact lenses, as trapped silica can be painful. If you can’t see without them, bring glasses or sunglasses, or take care to keep water off your face.

 

9. Wear Sunscreen and Sunglasses

You might not think of sunscreen before a hot soak, but the sun reflecting off the water can be strong, especially in summer. Iceland is one of the few places you can get sunburnt at 10pm, so use sunscreen at least on your face and upper body (and definitely on children). Sunglasses help too, as the glare off the water can be blinding on a bright day.

 

10. Stay Hydrated

Hot baths, saunas, and steam rooms are dehydrating, so drink plenty of water. You can bring a reusable bottle to refill (Icelandic tap water is safe and excellent). Your ticket includes a complimentary drink, and while the swim-up bar serves beer and wine, we’d go easy on alcohol, which only dehydrates you further. The blueberry smoothies are the better shout.

 

11. Shower Both Before and After Your Soak

There are plenty of reminders to shower before entering, but don’t skip the shower afterwards, to rinse the minerals off your skin and out of your hair. Moisturise heavily with the free lotion in the changing area, or your own. And rinse out your swimsuit thoroughly so the silica doesn’t damage it, using a provided plastic bag or your own breathable wet bag to carry it home.

 

12. Leave Plenty of Time to Enjoy It

A visit to the Blue Lagoon should feel relaxing. Once you’re in, you can stay until closing, so take your time exploring and soaking. Get your free mask and drink, poke around the steam room and lounge, and don’t book an entry slot too close to closing or to your flight. You don’t want to feel rushed, and giving yourself space is how you get your money’s worth.

 

When to Visit, and a Note on the 2026 Eclipse

The Blue Lagoon is open year-round, and the water stays the same temperature whatever the season, so it’s really the air temperature that changes. In summer the air is milder (it’s never really hot in Iceland), the sun is more likely to be out, and the lagoon stays open late into the light evenings. In winter there’s a striking contrast between the cold air and the warm water, the steam looks incredible, and if you stay past nightfall you have a small chance of catching the Northern Lights, though you’ll also contend with more rain or snow and a chilly dash in and out. Spring (roughly March to May) is usually the quietest time in Iceland, so it’s a good bet if you want to dodge the crowds.

Whatever the season, the least busy and least expensive slots are first thing in the morning and late in the evening. For the fewest people and the lowest prices, we’d book a morning slot around opening time. If you visit late, just double-check the closing time so you don’t cut your soak short.

A note for 2026: on 12 August 2026, Iceland will see a total solar eclipse, and the Blue Lagoon is selling special eclipse-viewing packages. It’s expected to be one of the most in-demand travel experiences in Iceland all year, so if you’re planning a visit around that date, book well in advance, as availability will be very limited.

Frequently Asked Questions

 

Is the Blue Lagoon worth visiting?

We think so, and we’ve been several times. It’s expensive, but it’s a unique experience you won’t find anywhere else, from the milky-blue water to the volcanic setting and the excellent facilities.

That said, it isn’t for everyone. If you’re on a tight budget, you may prefer one of Iceland’s many cheaper geothermal pools or free hot springs. For those who do go, we recommend the Comfort Package (it includes everything you need) and setting aside at least two hours to enjoy it.

 

Is the Blue Lagoon open in 2026?

Yes, as of July 2026 the Blue Lagoon is open and operating normally, with no active eruption. The Reykjanes Peninsula has seen ongoing volcanic activity since late 2023, and the Blue Lagoon has closed temporarily during some eruptions, reopening once the area was declared safe.

We recommend checking the Blue Lagoon’s seismic activity page before you book and again before your visit. If there’s a closure during your booking, you’ll receive a full refund.

 

How much does the Blue Lagoon cost?

The Blue Lagoon uses dynamic pricing, so costs vary by date and time slot. As a rough guide, the Comfort Package starts from around ISK 11,990, Premium from around ISK 14,990, and Signature from around ISK 18,490. The Retreat Spa starts from around ISK 89,000 per changing room for two guests.

Early-morning and late-evening slots tend to be cheapest. Children aged 2 to 13 visit free with a paying adult.

 

Do I need to book the Blue Lagoon in advance?

Yes, advance booking is mandatory. The Blue Lagoon uses a timed-entry system and regularly sells out, especially in summer. Walk-ins are rarely possible, so book as far ahead as you can, particularly between June and August.

 

What is the difference between the Blue Lagoon and Sky Lagoon?

The Blue Lagoon is the larger, more famous spa on the Reykjanes Peninsula, about 20 minutes from Keflavík Airport and 45 to 50 minutes from Reykjavík, known for its silica-rich milky-blue water and mud masks. The Sky Lagoon is a newer spa (opened 2021) just outside Reykjavík, with an infinity-edge pool overlooking the ocean and a 7-step bathing ritual.

The Sky Lagoon is slightly more expensive at the entry level, and its minimum age is 12, versus 2 at the Blue Lagoon, so families with young children should choose the Blue Lagoon.

 

Is it safe to visit the Blue Lagoon with the volcanic activity?

The eruptions on the Reykjanes Peninsula since 2023 have been localised and haven’t affected flights, Reykjavík, or the wider tourism infrastructure. The Blue Lagoon has built protective barriers and has well-practised evacuation procedures. The main risk is a temporary closure at short notice.

We recommend booking through a platform with free cancellation (such as GetYourGuide or Tiqets) and checking the latest status before your visit.

 

Does the Blue Lagoon water damage your hair?

The minerals, especially the silica, can leave your hair dry, stiff, and hard to manage for a few days, and the effect is stronger on color-treated hair. It isn’t permanent damage, though, and usually settles within a week.

To protect it, soak your hair in conditioner before going in and don’t rinse it out, tie long hair up, or wear a swim cap. Wash and condition thoroughly afterwards.

 

Can children visit the Blue Lagoon?

Yes. Children aged 2 and over can visit, and those aged 2 to 13 enter free with a paying adult. Children under 2 aren’t permitted, as the mineral content can be harmful to very young skin, and children aged 8 and under must wear arm floats (provided free on-site). Each adult can supervise up to two children. The minimum age for the Retreat Spa and Retreat Lagoon is 12.

 

How long should I spend at the Blue Lagoon?

We recommend at least two hours to enjoy the pools, plus time for changing and showering before and after. Most visitors spend two to four hours in total. There’s no time limit once you’re in, so you can stay until closing. If you’re visiting on the way to or from the airport, allow about three hours to be safe.

 

How long does it take to shower, change, and get into the pool?

Most people get through check-in, changing, and the required pre-swim shower in about 15 to 20 minutes if there are no long queues. Afterwards, allow 20 to 30 minutes for showering, drying, changing, and packing up wet items. Add time if you plan to blow-dry and style your hair.

 

Can I submerge my face or go underwater in the Blue Lagoon?

Yes, you can put your head underwater. The water isn’t clear (because of the silica), so it isn’t really a place for swimming laps, and it’s shallow, averaging around 1.2 m (4 ft) and no more than about 1.4 m at its deepest, so most people can simply stand. Children can play and go under. Just be aware that silica can irritate your eyes, so the Blue Lagoon strongly recommends removing contact lenses first.

 

Can I visit the Blue Lagoon if I don’t want to swim?

You’re welcome to visit the café, restaurant, and gift shop without a ticket, and you can see parts of the lagoon through the café windows and from a viewing area. But you can’t enter the bathing area, locker rooms, or spa without a ticket and wristband.

The café can be a decent spot to wait if not everyone in your group is bathing (bring a book), but beyond eating or shopping, there isn’t much else to see, so it’s not really a stop worth making on its own.

 

Can I stay overnight at the Blue Lagoon?

Yes. There are two on-site hotels: the Silica Hotel, which includes access to a quieter private lagoon (rooms from around ISK 90,000 a night), and the five-star Retreat Hotel, attached to the Retreat Spa and the Michelin-starred Moss Restaurant (rooms from around ISK 220,000 a night, usually with a two-night minimum).

Nearly everyone who visits Iceland makes a stop at the Blue Lagoon. It’s iconic, beautiful, and relaxing, and we hope this guide helps you decide whether it’s right for your trip, and have a great visit if you go.
