Among the geothermal spas in Iceland, two stand out as the most well-known: the Blue Lagoon and Sky Lagoon. The Blue Lagoon, famed for its milky-blue waters, and the Sky Lagoon, with its dramatic cliffs and infinity edge, both offer the ultimate relaxation.

So which experience is the best? Read on to learn everything you need to know about visiting the Blue Lagoon and the Sky Lagoon on your trip to Iceland. Let the battle of the spas begin!

The Blue Lagoon: Where It All Began

Aerial view of the Blue Lagoon in Iceland, with milky-blue geothermal waters set among black lava fields and surrounding hills.The Blue Lagoon, located in an 800-year-old lava field on the Reykjanes Peninsula, is one of Iceland's most iconic attractions, drawing visitors from around the globe. This geothermal lagoon was formed in 1976 during operations at the nearby Svartsengi Power Plant. As the hot, mineral-rich water used to generate electricity was released into the surrounding lava field, it began to accumulate, forming the pool that is now the Blue Lagoon.

The milky-blue waters of the Blue Lagoon contrast starkly with the surrounding black lava rocks. The lagoon's striking color is due to its high silica content, which reflects sunlight and gives the water its unique hue. The temperature of the water averages around 98-102°F (37-39°C), and it's rich in silica and minerals that are said to have healing properties.

It's also said to be particularly beneficial for people with skin conditions like psoriasis. These benefits are the foundation of the renowned Blue Lagoon Skincare line.

The unique mineral content of the water does mean that you will have to take special care of your hair when going to the Blue Lagoon. If it gets wet, you may find that your hair will have a straw-like texture afterward that will go away after a few days. The minerals don't actually damage your hair long-term, but can be a bit bothersome before your hair texture gets back to normal.

To prevent this, make sure to use a lot of the lagoon's complementary conditioner and keep it in your hair while you're in the water to protect your hair. You can also keep your hair out of the water, but of course, that is easier said than done.

The Blue Lagoon is designed to blend with the volcanic rock of the surrounding area, featuring modern buildings with a futuristic appearance inspired by nature. The lagoon itself is man-made but appears entirely natural, adding to the harmony between architecture and the environment.

You'll find many crevices and caves in the water, which offer more privacy, with walking paths and bridges on the edges of the water. If you want to find the most affordable ticket to the Blue Lagoon or stay close to the iconic spa, make sure to book ahead of time.



The Sky Lagoon: Comfort in the Capital

Situated on the edge of the Atlantic Ocean within the capital region, the Sky Lagoon offers an unparalleled geothermal spa experience that fuses natural beauty, Icelandic tradition, and modern luxury. Opened in 2021, it quickly became one of Iceland's must-visit destinations, bringing a unique twist to the country's famous geothermal bathing culture.

The geothermal waters in the Sky Lagoon are warm and comforting, typically maintained at a temperature of around 100-104°F (38-40°C). Coupled with breathtaking views of the mountains, ocean, and skies, it offers an immersive experience that seems to blur the boundaries between the man-made lagoon and the natural world.

The Sky Lagoon's most distinctive feature is its impressive 70-meter infinity-edge pool. The pool's edge appears to merge with the vast Atlantic Ocean, creating an illusion of endless water that seamlessly blends with the surrounding sea. The architecture is distinctly modern yet pays homage to traditional Icelandic design principles, utilizing clean lines, minimalistic aesthetics, and natural materials.

This is part of a special seven-step ritual, where guests go through relaxing experiences that play with the beneficial effects of heat and cold for the body. 

The ritual also includes the Sky Body Scrub, an iconic part of the Sky Lagoon skincare line. If you like some of the products during your visit, you can purchase them on-site before heading back to your hotel.

The entrance of the spa area mimics a traditional Icelandic turf house, and the same inspiration can be found on the outside of the main building. The main entrance of the Sky Lagoon is lined with a turf wall, built using the same technique as in historical Icelandic turf houses. There are very few people left in the world who know how to build from turf in this traditional way, making the outside design of the Sky Lagoon quite an accomplishment.

Even with all the aforementioned features that make Sky Lagoon a great place to visit, at the top of the list is probably its destination. It is only a 10-15 minute drive away from Reykjavik's city center, located in the suburban town of Kopavogur. This makes it highly convenient to visit if you're considering hotels in Reykjavik, as you won't have to leave the capital region to get there.

The Location of the Lagoons

Entrance to the Blue Lagoon surrounded by lava and with a beautiful sunset in the backgroundThe Blue Lagoon and Sky Lagoon offer exceptional geothermal spa experiences but have significantly different settings, though all are within driving distance from Reykjavik. Whether you prefer a location within city limits or don't mind a short journey, accessibility is something to account for.

Location of the Blue Lagoon

Building of the Blue Lagoon with nature in the backgroundThe Blue Lagoon is situated amidst the rugged, otherworldly volcanic landscape of the Reykjanes Peninsula. It's an approximately 50-minute drive from Reykjavik and about a 20-minute drive from Keflavik International Airport. It's most convenient to reach by car, and you can easily pick up a rental car by Keflavik Airport for convenience.

There are also many Blue Lagoon tours available if you prefer not to drive or plan to take advantage of their in-water bar. You can choose the quick Blue Lagoon shuttle bus from Reykjavik or transportation to the Blue Lagoon from Keflavik Airport for the start of your visit. Then you can take advantage of the return transfer to Reykjavik or Keflavik Airport, which even includes the comfort admission ticket in the pricing!

We also recommend pairing your Blue Lagoon trip with another experience. Take the time to explore the surrounding natural wonders with a self-drive tour, or choose from the many guided Reykjanes tours available.

There are even multiple tours from Reykjavik that offer the Blue Lagoon as part of the journey, like this highly-rated Golden Circle and Blue Lagoon tour, which we recommend checking out.



Location of the Sky Lagoon

People entering the sky lagoon with cliffs above the waterThe Sky Lagoon is located in the Karsnes harbor area in the municipality of Kopavogur in the capital region. This proximity to the capital makes reaching Sky Lagoon very easy, as it's only about a 15-minute drive from downtown Reykjavik.

The city bus, taxi, or rental car in Reykjavik are all viable options for transportation. You can also book a convenient transfer to the Sky Lagoon from your hotel in Reykjavik.

The in-city location doesn't affect the relaxation, however. Because of the lagoon's positioning in Skerjafjordur bay, you'll feel separated from the noise of the bustling capital during your visit and be able to unwind in peace.

Price Range, Experiences, and Spa Rituals

The spa experiences of the Icelandic geothermal lagoons are quite luxurious, but you can choose from differently priced entrance passes and customize your visit in other ways. Choose the option that best fits your needs and interests, but keep in mind that the prices mentioned may change with time.

Entry to the Blue Lagoon

You can book a Blue Lagoon Comfort ticket for the most affordable entry at around 107 USD. It's slightly more affordable if you go at opening time or later in the evening. Along with entrance to the lagoon, it includes a silica mud mask and a drink of your choice to enjoy as you relax in the water. You also get access to a towel, so you don't have to bother with bringing your own.

Your second option is to book a Blue Lagoon Premium ticket, which costs around 125 USD. It's a great way to maximize your experience. It includes the same benefits as the Comfort entry, but you will also get a cozy bathrobe during your stay and two additional mud masks of your choice. If you're planning on dining at the Blue Lagoon Lava restaurant, then you will also get a complimentary glass of sparkling wine with this access!

Man and woman at the sauna of the Retreat Spa at the Blue Lagoon in IcelandThey also offer a third luxury access option, which gives access to their amazing Retreat Spa and costs around 642 USD.  You'll get a private changing room and access to a more private part of the area known as the Retreat Lagoon.

This option is especially beneficial if you're curious about the famous skincare line of the Blue Lagoon, as you can try some of their products as part of their Blue Lagoon Ritual treatment before making a purchase. Additionally, you will have access to the Spa Restaurant.

Entry to the Sky Lagoon

You can book the Sky Lagoon full-access ticket, known as "Saman entry," which gives you access to the main pool area of the lagoon. Take in the beautiful view from the infinity edge before enjoying the relaxing seven-step ritual. It also includes a towel, so you don't have to bring your own.

The first step of the Sky Lagoon ritual is enjoying the main geothermal pool. You then take a dip in cold water, which is intended to stimulate your immune system and reduce inflammation while giving you an endorphin rush.

After that, you exfoliate your body with the Sky Body Scrub, and then the penultimate step is a steam bath, where you'll be able to maximize the hydrating benefits of the scrub. Once you're content, you take the last step, which is enjoying a taste of Iceland with a crowberry elixir, before returning to the main geothermal pool.

If you want more privacy during your visit, you can book a Sky Lagoon premium ticket. This entry, called the "Sér entry," gives you access to all the aforementioned activities with the benefit of a private changing room.

Opening Times and When to Visit

Sunset at the Blue Lagoon in IcelandThe Blue Lagoon and Sky Lagoon both offer extended opening hours to suit a wide group of guests. Your experience may have different advantages depending on what time of year you're traveling to Iceland and what time of day you book your visit. Also, be aware that exact opening times may change.

When to Visit the Blue Lagoon

The Blue Lagoon’s opening hours change with the seasons, giving visitors a chance to enjoy its geothermal waters at different times of day. During the summer months, from 1 June to 20 August, it is open from 07:00 to 00:00, letting you experience the lagoon beneath the glow of the midnight sun.

For the rest of the year, from 21 August to 31 May, the lagoon is open daily from 08:00 to 22:00, offering long evenings of relaxation during Iceland’s quieter travel season. On special holidays, the hours are shorter: the lagoon closes at 16:00 on Christmas Eve and at 18:00 on New Year’s Eve.

People at the Blue Lagoon with the in water bar in the background and bridges on the edgeAs the Blue Lagoon is arguably the most famous attraction in Iceland, you can expect a lot of people when you're visiting. What's helpful, however, is that you have to book a specific time for your arrival, which means that it shouldn't be too packed in the changing room.

There's no limit to how long you can stay in the water, but people generally spend up to three or four hours relaxing at the Blue Lagoon. This will depend on which entry pass you booked and whether you choose to eat at their restaurants.

If you want to visit but prefer to avoid crowds, we recommend going in the late afternoon or early evening, as it's likely to be less crowded. The area is also very large and has many nooks and crannies, so even if the lagoon is fully booked, you can find more privacy if you move away from the main entry area.

It's also much better to go during the low season, as there are fewer people, and you can enjoy the twilight and the starry night sky. If you're lucky, you may even be able to spot the northern lights in the winter darkness!

When to Visit the Sky Lagoon

Waterfall at the Sky Lagoon in IcelandThe Sky Lagoon’s opening hours vary throughout the year. During the winter months, from 1 November to 31 May, the lagoon is open Monday to Friday from 11:00 to 22:00 and Saturday to Sunday from 10:00 to 22:00.

As summer arrives, hours are extended to make the most of the long days. From 1 June to 30 June, the lagoon is open daily from 09:00 to 23:00. Between 1 July and 31 August, it opens Saturday to Thursday from 08:30 to 23:00, and on Fridays from 08:00 to 23:00.

In early autumn, from 1 September to 30 September, the lagoon is open daily from 09:00 to 23:00. Meanwhile, in October, it shifts slightly, with daily hours from 10:00 to 22:00.

People at the Sky Lagoon with the capital area in the backgroundIf you tend to start your day early, we recommend enjoying a lovely breakfast or brunch in Reykjavik or the nearby capital area before going to unwind in the relaxing water at opening time. However, like the Blue Lagoon, it will be less crowded in the evening, which is the best time to go.

One of the magical city experiences of the darker months in Iceland is visiting the Sky Lagoon in the early evening and staying until closing. Because of the stunning ocean views, you can experience the beautiful sunset reflecting on the water as the sky transitions into darkness. If you're visiting during the darkest months, you may also be able to spot the northern lights or at least enjoy the starry sky on a clear night.

The beautiful facilities of the Sky Lagoon in Iceland

The Sky Lagoon is very popular, but it likely won't be as crowded as the Blue Lagoon. You can still expect a lot of people, especially if going during the high season. The area is also smaller than the Blue Lagoon, and the most crowded area is along the glass infinity edge, but you can find more privacy along the cliffs and at the bar area. You also have to book a certain time for entry, so the changing rooms should not be too crowded when entering.

There's no limit to how long you can stay during opening time. It's common to spend between three and four hours, but this depends on whether you choose to include the spa access in your trip and if you plan to grab a bite to eat afterward.

Food and Drink Options

The bar area of the Sky Lagoon in IcelandYou're likely to be spending a while relaxing at your geothermal spa adventure, so one of the factors to consider when choosing a location is the food available. Both locations offer a range of food and drink options, but there are some differences to consider depending on what kind of experience you're seeking.

Food at the Blue Lagoon

Blue Lagoon caféThere are multiple locations at the Blue Lagoon where you replenish your energy. For the quickest and most casual experience, you can grab a bite at the Blue Café. It's an especially good option for an easy breakfast if you're arriving early. You can also order drinks, both with and without alcohol, at the in-water bar.

For a more formal experience, there are several restaurant options to choose from. Their most popular one is the Lava Restaurant, which offers a beautiful view of the blue water. They offer a fine dining experience that focuses on Icelandic cuisine. If you choose the Premium Pass to the Blue Lagoon, you will get a complimentary glass of sparkling wine for your meal!

Food at the Sky Lagoon

People enjoying food at the Sky Lagoon in IcelandSky Lagoon also offers great food inspired by Icelandic and Nordic food culture. You can order a tasting platter at the Smakk Bar for yourself or for sharing. You could also grab a tasty treat at the Sky Café. These options are a good way to end your trip to the Sky Lagoon, but be aware that you must order at least 30 minutes before closing time, so account for that in your plans.

While they offer great drinks along with their food options, you must take advantage of their in-water bar while you relax in the lagoon. There's a three-drink limit per person, and they have many options with or without alcohol.

Accommodation Near the Lagoons

There are many accommodation options to choose from, so you're sure to find something to suit your needs and preferences.

The Sky Lagoon is located within the capital area, so it's likely no surprise that it doesn't offer its own accommodation options. You can, however, find accommodation in Kopavogur for optimal convenience.

You can also easily stay in accommodation in Reykjavik if you want to visit the Sky Lagoon, though it's best reached by rental car. No matter where you stay in the capital area, you'll have an easy time getting to the Sky Lagoon with either a rental car, taxi, or city bus.

Woman by a cave at the Blue Lagoon in IcelandIf you're looking for accommodation at the Blue Lagoon, you have a few options. The lagoon itself offers two choices: the luxurious Retreat Hotel and the Silica Hotel. Both provide exclusive guest-only areas and a complimentary Premium Experience at the Blue Lagoon.

Moreover, The Retreat Hotel, with its suites offering lagoon views, also houses the Michelin-star Moss Restaurant and the Lava Cove spa. Beyond these on-site stays, travelers will also find some of the best hotels near the Blue Lagoon in Iceland, offering a wider range of styles and price points just a short drive away.

You can also stay in the nearby towns of the Reykjanes peninsula if you have a rental car. You can book different types of hotels in Keflavik, one of the closest towns to the Blue Lagoon.

If you're planning a Blue Lagoon visit for your first or last day in Iceland, you may rather want to stay in accommodation near Keflavik Airport. Travelers who prefer more curated stays can explore the best hotels near Keflavik Airport, which highlight top-rated options chosen for both comfort and convenience.



Age Limit and Water Depth at the Lagoons

If you're traveling with children, be aware that the Blue Lagoon and Sky Lagoon both have some form of age limitation for entry. This varies by location, but it's something to account for in your travel plans.

For the most family-friendly location, the age limit for the Blue Lagoon is 2 years old. Children between the ages of 2 and 13 get free entry, though they have to share a locker with a parent or guardian. For the Sky Lagoon, the age limit is 12 years old, and an adult guardian must accompany any children under 18.

In the Blue Lagoon and Sky Lagoon, the water is rather shallow, so you don't have to worry about the depth. It's around the hip level of the average adult, and you also don't have to know how to swim to enter.

Wheelchair Accessibility

Wheelchair ramps at the entrance for wheelchair accessibility at the Blue Lagoon in IcelandBoth the Blue Lagoon and the Sky Lagoon offer commendable wheelchair accessibility. The Blue Lagoon ensures ease of entry through a private changing area, a specially designed pool access and lift to enter, and loaned wheelchairs for in-water use. Similarly, the Sky Lagoon's inclusivity features a ramped entrance, a spacious changing room, and wheelchair-friendly pathways.

Both places deliver impressive accessible amenities, although the Blue Lagoon’s in-water wheelchair may be a unique advantage for some visitors. Consequently, their commitment to inclusivity makes them welcoming destinations for all visitors.



What To Know About Icelandic Bathing Culture

Woman relaxing at the Blue Lagoon in IcelandSwimming is an integral part of Icelandic culture, with both recreational and health benefits highly valued by locals. The tradition of swimming in Iceland is influenced by the abundance of geothermal energy, which heats the country's many pools, lagoons, and natural hot springs. Swimming lessons are also compulsory in the Icelandic education system, instilling a strong culture of swimming from a young age.



Cleanliness

Showers and changing rooms of the Hvammsvik Hot Springs in IcelandThere are some things you need to know about the Icelandic swimming culture before visiting any lagoon, spa, or swimming pool in the country. Icelanders emphasize the cleanliness of their public bathing facilities, so you should be aware that it's mandatory to shower without a swimsuit before soaking in any public body of water.

This is done to maintain the water's purity and out of respect for your fellow visitors. It's also recommended to shower well afterward. You'll find free soap at any public swimming location in Iceland.

Many locations that are popular among travelers, like the Blue Lagoon and Sky Lagoon, offer closed shower stalls so those not accustomed to public showers can enjoy some privacy. The Blue Lagoon and Sky Lagoon also offer private changing rooms for an additional price.

Lagoons, Pools, and Hot Springs around the Country

Geothermal Power in Iceland

Geothermally heated water is one of Iceland's most valuable natural resources. This provides the country with a sustainable source of heat and electricity.

This use of geothermal power in Iceland comes from the island’s unique position on a hot spot in the Earth's crust called the Mid-Atlantic Ridge. Here, abundant volcanic activity heats underground reservoirs of water. This geothermally heated water can emerge naturally as hot springs, or it can be harnessed through boreholes to supply the country with hot water.

All outdoor and indoor swimming pools in Iceland are heated, so you don't have to worry about missing out when visiting during the colder months. In fact, many Icelanders will tell you that the best time for swimming is when it's cold outside, especially if it's raining or snowing! The refreshing cold makes relaxing in the hot water even more enjoyable.

FAQ's about Visiting Geothermal Lagoons in Iceland

Woman enjoying the view from the Sky Lagoon in IcelandHere are some of the most frequently asked questions about visiting lagoons in Iceland.

Can you wear jewelry at the Blue Lagoon?

It's recommended not to wear jewelry in the Blue Lagoon. The mineral-rich waters, while beneficial for the skin, can cause discoloration and build-up of dirt in jewelry. It's also generally a good idea to remove jewelry before entering the Sky Lagoon and any other geothermal lagoon, pool, or hot spring.

Does the Blue Lagoon smell?

Flip-flops are not necessary but can be useful. The floor tends to be uneven and rough in places, though most visitors go barefooted.

Can the Blue Lagoon damage your bathing suit?

The mineral-rich water of the Blue Lagoon won't ruin your bathing suit, but it can leave a residue. It's suggested to rinse your suit thoroughly in fresh water after use. Some visitors choose to wear an older suit or rent one during their visit.

So, Which Spa Is The Winner?

Woman relaxing at the Blue Lagoon in IcelandThe Sky Lagoon and Blue Lagoon in Iceland both offer unique experiences, leaving visitors charmed by their beautiful vistas. As each one has different characteristics, it makes it nearly impossible to choose a clear winner, as everyone will have a different opinion, and honestly, they're both pretty amazing.

The truth is, there isn’t a single winner. There’s just the one that’s right for you.

The Blue Lagoon is ideal if you’re looking for a world-famous destination with therapeutic geothermal waters, silica-rich mud masks, and a luxurious spa atmosphere. It’s the classic choice for travelers who want to experience Iceland’s most iconic bathing spot.

On the other hand, the Sky Lagoon is perfect if you prefer something more intimate and closer to Reykjavik. With its stunning infinity-edge pool overlooking the Atlantic Ocean and the seven-step ritual blending hot, cold, and relaxation, it offers a more serene and immersive wellness journey.

Both are worth experiencing, so if time allows, visiting both can give you the best of Icelandic spa culture. But no matter which you choose, you’ll walk away refreshed, relaxed, and carrying a piece of Iceland’s natural magic with you.
