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 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.
