1. What is the Blue Lagoon?

Blue Lagoon

The Blue Lagoon is the most popular spa in Iceland. It owes its name to the milky-blue water as a result of the way silica reflects the light. Silica is the most abundant element in the water.

The lagoon is formed due to the geothermal seawater pumped out from the geothermal plant Svartsengito to the nearby lava field after heating fresh water for domestic use. The silica from the water separated after the cooldown, forming a mud layer in the lava that stopped the water seeping through, creating the lagoon.

The lagoon was used for the first time for a man suffering from psoriasis to relieve his skin. After the positive effect on his skin, a public bathing facility was opened in 1987 for people with similar skin problems. It didn’t take long after that for locals to start going too to the hot spring.

The Blue Lagoon is ideally located on the Reykjanes Peninsula, 20 minutes from Keflavík International Airport and 40 minutes from downtown Reykjavík, with the usual traffic.

The Blue Lagoon does not close for bad weather (like rain or wind); it will only close for extreme weather conditions, which have only happened 3 times in the last decade.

It has, and once you check in the reception, you will get an electronic hand band that, between many things, also works to close your locker. Just choose any vacant locker and follow the instructions about how to lock it.

The locker area is together with the changing room, which is divided into men and women. From there are a few meters to the lagoon. If you need to take something or store something in the lockers after you are in the lagoon, you can just go and come back without any problem.


The locker in the changing area has an excellent size to store your clothes, shoes, and a medium bag and is included in the ticket price.

Nudity is not allowed in the Blue Lagoon; you need to wear always swimwear. If required, swimwear can be rented for 800 ISK (5.30 €/$6.20), or you can buy one at the Blue Lagoon shop.

The Blue Lagoon’s official website report that:

The Blue Lagoon’s geothermal seawater will not ruin your swimsuit or cause permanent stains. However, we recommend rinsing your swimsuit with cold water and soap after using the lagoon.

It is recommended that you remove any jewelry before entering the lagoon to avoid losing your items and that they don’t get damaged by the high levels of silica, algae, and minerals in the water.

12. What to bring to the Blue Lagoon?

Basically, you can come empty hand just with your pre-booked ticket. But if you don’t want to spend money buying or renting a swimsuit, this is the peace that you can not forget.

As mentioned before, you will have access to a locker where you can let all your belongings. That can be locked with an electronic bracelet that is included in the ticket price. If you want to access the lagoon with your phone, we recommend bringing a waterproof phone case.

After the locker, you will have access to the shower room where shower gel, shampoo, and conditioner are provided for free; here is recommended to use some conditioner in your hair during all your time in the lagoon, since the silica from the water might dry your hair. Some people prefer to bring and wear a swim cap.

You can also wear sunglasses in the lagoon. However, it is recommended to do so on sunny days for the water’s reflective properties.

After you finish in the lagoon, you have access to clean towels, but if you prefer, you can bring yours. If you have the premium tariff, you also will have access to some ropes and slippers. Honestly, we didn’t need this since we spend all the time inside the lagoon, but if you would like, you can bring yours or rent one for 1500 ISK (10 €/$11.50) each.

For your wet swimwear, they provide little plastic bags next to the towel rack so you can store wet swimsuits in your bag.

13. What to do at the Blue Lagoon?

The Blue Lagoon is not just about the geothermal lagoon (even though this is the most visited area and was the only facility we visited during our day there). Inside the lagoon, you can just enjoy and relax in the geothermal seawater, but you can also enjoy some drinks (alcoholic and non-alcoholic), the 1st one is already included in the entrance fee, but using your electric hand band you can buy more, which you can later pay at the checkout. There is also the mask bar inside the lagoon, where you can take your silica mud mask included in the price and the second mask of your choice for those with premium tickets. Silica enhances the skin’s barrier function, bringing strength, protection, and radiance.

You can also take an in-water massage in private are of the lagoon for an extra fee. Appointments for this massage can be sold out, so book your calling or send an email days before your visit. Check in this link for the contact information and prices.

Other activities of the lagoon area are the sauna/steam room, the lagoon waterfall, and the viewing deck.

Other facilities and activities:

  • The Blue lagoon store is the perfect place to dose skincare lovers to discover the benefits of silica and buy some of the products they offer.
  • The Retreat Spa, for those looking for a luxury experience in the Blue Lagoon. This includes 5 hours of access to the Blue Lagoon, the retreat Lagoon, and many other advantages.
  • Dining area, from cafes and snacks to a magnificent dinner in one of the gourmet restaurants.

14. What is the temperature of the Blue Lagoon?

The water temperature reported for the official blue lagoon website is generally between 37°C and 40°C (98-104°F), with some fluctuation beyond this range depending on the weather conditions and the season.

15. Is it natural the Blue Lagoon?

The Blue Lagoon is not natural. It is formed for the wastewater from the Svartsengi power plant. The water is a mix of dissolved minerals and seawater. Direct use for warm-up houses might damage the pipes due to the minerals. So instead, it is used to heat fresh water that is then pumped to nearby urban areas. After this, the water is released into the lagoon.

The natural minerals have been proven to be very good for people’s skin. Since the water is continually streaming into the lagoon, all of it is renewed in 40 hours, making sure it stays clean. Regular sampling of this natural resource shows that foreign bacteria do not thrive in the lagoon’s ecosystem. Thus, disinfectants such as chlorine are not needed. In essence, the lagoon is a self-cleaning ecosystem.

The bottom of the lagoon is smooth and soft. It is naturally uneven, but you don’t need to worry about encountering anything sharp or jagged.

16. How deep is the Blue Lagoon?

The depth at the lagoon’s edge is ~ 0.8m/2.6f. The further into the water you go, the deeper it gets, with the greatest depth of 1.4m/4.7ft.

You don’t need to know how to swim to visit the Blue Lagoon; you can stay in the areas where the water is shallow enough that it doesn’t pose a danger to non-swimmers. Children from 2 to 8 years old are required to wear floaties which are provided. To assure the safety of all guests, there are lifeguards on duty at all times.

17. How to protect your hair at the Blue Lagoon?

While geothermal seawater is beneficial for the scalp, it can leave the hair dry. For this reason, it is recommended to use a conditioner before and after the lagoon or to use a swim cap.

18. Where to stay to visit the Blue Lagoon?

The 3 more common options are two stays in the city of Keflavik if you are heading the next day to the airport, stay in Reykjavik (this was the option we used), or two stays in one of the two Blue Lagoon hotels:: The Retreat Hotel or Silica Hotel.

The Blue Lagoon is the most popular but not the only hot spring in Iceland. Other popular hot springs include:

And some of the free ones:

20. Is it worth visiting the Blue Lagoon?

First among the country’s many simmering geothermal pools is the Blue Lagoon, a turquoise vision in a black basaltic moonscape.

National Geographic Wonders of the World

Personally, we will say YES! Is it overrated? Probably YES!

Let us explain: We really enjoyed the experience. We felt our bodies extremely relaxed after our time in the lagoon. So for us was the perfect end of the road trip. But if you are looking just to relax in a hot spring, if the hot water is what you want without considering the localization, the best option would be to enjoy one of the free ones or one of the other lagoons that are cheaper.

Would we repeat the experience? Probably YES! But honestly, mostly to take as many photos as possible with a proper camera, because the best of the Blue Lagoon is unique in the beauty of the blue water in contrast with the lava field (apart from its excellent location).
