The Definitive Guide to The Blue Lagoon in Iceland

The Blue Lagoon is undoubtedly an experience not to be missed during a trip to Iceland. While there are many other hot springs, spas, and man-made pools in the country, none are as iconic and instantly recognizable as the Blue Lagoon.

What is the Blue Lagoon?

The Blue Lagoon is one of Iceland’s top tourist attractions, becoming so popular in recent years that travelers are advised to make a reservation days or even weeks before their trip. This man-made geothermal pool attracts people from all over the world who want to soak in the warm, milky blue water.


The Blue Lagoon is open year-round and maintains a temperature of 39℃. The spa was originally formed for people who suffered from psoriasis or other skin conditions, as the warm, mineral-rich water proved to be extremely beneficial in treating skin problems.

The Blue Lagoon’s Hotel

The Retreat Hotel, Iceland’s first five-star hotel, was opened by the Blue Lagoon in 2018. The 62 suites have floor-to-ceiling windows with stunning views of the lava fields. The Retreat Spa is the epitome of luxury travel, with a pool, steam room, cold well, yoga, water massages, and many other treatments and services available for guests. The spa is accessible for all guests of the Retreat Hotel.


The Silica Hotel is only for adults 18 and up. This hotel has its own private lagoon and complimentary Premium admission to the Blue Lagoon.

The Water in the Blue Lagoon

Although it isn’t known for sure why the water found in the Blue Lagoon is so beneficial to skin, it is likely due to a combination of the minerals, bacteria, and algae in the water. The water in the Blue Lagoon contains dissolved minerals, including calcium as well as chloride and natron which together make sea salt. The water also has trace amounts of magnesium, sulphur, and carbonate. The Blue Lagoon is home to a certain type of bacteria that has not been found anywhere other than in the lagoon. The blue-green algae that thrives in the lagoon gives the water its distinct blue color.

Buildings are low and constructed with natural materials such as wood and lava to keep the area feeling natural. The nearby Lava Restaurant has one solid lava rock wall as it was built around a lava cliff. The area is intentionally designed to be simplistic and in harmony with nature.
