The Blue Lagoon geothermal spa is one of the most visited attractions in Iceland. The steamy waters are part of a lava formation.
The warm waters are rich in minerals like silica and sulphur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases. The water temperature in the bathing and swimming area of the lagoon averages 37-39 °C.
The lagoon is fed by the water output of Svartsengi, the nearby geothermal power plant, and is renewed every 2 days. The water is fed into the lagoon for recreational and medicinal bathing.
The spa is located in a lava field in Grindavik on the Reykjanes Peninsula, southwestern Iceland. The Blue Lagoon is situated approximately 13km from the Keflavik International Airport and 39km from the capital city of Reykjavik. That is roughly a 20 minute drive from the airport and a 40 minute drive from Reykjavik.
