The Blue Lagoon geothermal spa is one of the most visited attractions in Iceland. It also known as “The Land of Fire and Ice”, because you are swimming in mud waters while it is snowing outside. The steamy waters are part of a lava formation. The warm waters are rich in minerals like silica and sulfur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases like psoriasis. The water temperature in the bathing and swimming area of the lagoon averages 37-39 °C.
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. Though the lagoon looks like something born from Iceland’s otherworldly landscape, it is actually man made. It was created by run-off from the Svartsengi power plant, which pumps up the geothermally heated water from a full mile below the surface. After being used to generate both heat and electricity, the excess (which is absolutely clean) is ejected into the lagoon.
