Blue Lagoon
Iceland's World-Famous Geothermal Spa
Iceland's most famous attraction, the Blue Lagoon is a man-made geothermal spa fed by the waste water from the nearby Svartsengi geothermal power plant. Its milky blue waters are rich in silica, algae, and minerals.
The Waters
The Blue Lagoon's signature milky blue color comes from the high concentration of silica suspended in the water. The geothermal seawater originates 2,000 meters below the surface, where it is heated by volcanic activity before rising to the surface at approximately 240 degrees Celsius.
After being used in the Svartsengi power plant to generate electricity, the mineral-rich water flows into the lagoon at a comfortable bathing temperature, creating one of the most photographed destinations in Iceland.
