Find your peace at the Blue Lagoon hot springs

The Blue Lagoon Iceland geothermal spa is an iconic and magical destination, located on the Reykjanes peninsula. This worst-kept-secret lagoon offers the perfect destination to relax and let your worries drift away in the hot water of these natural hot springs.

The otherworldly Blue Lagoon is one of the most exquisite geothermal pools in Iceland. This incredible geothermal spa is located in 800-year-old lava fields, directly in front of the mighty Þorbjörn mountain.

Nowadays, the Blue Lagoon is known for luxury and relaxation. However, its origins are a little unorthodox. At first, it was fed by wastewater from the Svartsengi geothermal power plant. Knowing this, people were understandably nervous about bathing in the blue water.

However, in 1981, local Valur Márgeirsson discovered the health-promoting properties of the water. He and others soon began to bathe in the lagoon to see if it would help with chronic skin problems, which it did. The water has since been tested and found to help with conditions such as psoriasis and dermatitis.

As well as its stunning surroundings and healing waters, the Blue Lagoon also offers beauty and massage treatments for that luxury spa experience. 

What’s more, you can dine with a view over the lagoon at one of the 3 innovative restaurants in the complex, including the Lava Restaurant and Moss Restaurant.
