The Blue Lagoon geothermal spa is one of the most visited attractions in Iceland, and easily the most photographed. The spa is located in a lava field in Grindavík on the Reykjanes Peninsula, southwestern Iceland, approximately 13km from the Keflavik International Airport. Though the lagoon looks like something born from Iceland’s otherworldly landscape, it is actually man made. The lagoon was created by run-off from the nearby Svartsengi power plant, which pumps up the geothermally heated water from a full mile below the surface. After being used to run turbines that generate electricity, the excess water is fed into the lagoon. The water is renewed every 2 days.
The warm waters are rich in minerals like silica and sulfur and bathing in the Blue Lagoon is reputed to help many people suffering from skin diseases such as psoriasis. The water temperature in the bathing and swimming area of the lagoon averages 40 °C (104 °F) and is enjoyable year round, even in freezing conditions.
In addition to the lagoon, there's a sauna, steam bath carved out of a lava cave and a massaging waterfall. A shop, café and viewing deck keeps spectators amused.
