Blue Lagoon - Bláa Lónið

Geothermal wonder
A visit to the Blue Lagoon Iceland geothermal spa is an important part of your stay in Iceland. Guests renew their relationship with nature, soak up the scenic beauty and enjoy breathing the clean, fresh air while relaxing in the warm geothermal seawater. It is no surprise that the readers of "Conde Nast Traveller" voted Blue Lagoon as the best medical spa worldwide. For five consecutive years Blue Lagoon has been awarded the Blue Flag environmental recognition granted to natural beaches and marinas.


The water's temperature is 37-39°C / 98-102°F. The lagoon holds six million liters of geothermal seawater, which is renewed every 40 hours. Regular sampling shows that "common" bacteria do not thrive in this ecosystem, thus additional cleansers such as chlorine are not needed.

The Blue Lagoon geothermal seawater is a part of an ecocycle where nature and science work in harmony. The seawater originates 2000 meter/6562 ft beneath the ground where it is heated by earth's natural forces. At this depth the temperature is 240°C/464°F and the pressure is 36 times the pressure on the earth's surface. The geothermal seawater comes into contact with cooling magmatic intrusions and captures the earth's minerals, resulting in this unique natural source known for its healing power and actives.

The composition of minerals in the water is very distinctive and has a high level of silica. Its environment is characterized by high temperature and salinity level of 2.5% which is 1/3 of the ocean's salinity level.

Research and Development
Product DevelopmentThe geothermal seawater is brought to the lagoon for people to enjoy bathing in it, and to the R&D centre where its actives are isolated for use in Blue Lagoon skin care.

Research and development has from the beginning been one of the pillars of Blue Lagoon's operations. The R&D team works with some of the world's most distinguished scientists, creating a strong, professional network and acquiring knowledge in bio-technology, dermatology and marine.
