Reykjavik to Blue Lagoon: Private day trip

Contrary to popular belief, the Blue Lagoon is not a natural formation, but the excess water from the nearby geothermal plant that opened in 1976. Like elsewhere in Iceland, the plant uses naturally heated seawater to heat fresh water, which is then used to heat people’s homes. When this seawater is no longer hot enough, it’s pumped out into the lava field to be reabsorbed by the earth. However, the waters at the Svartsengi geothermal power station were so rich in silicates that they coated the porous lava rocks with mud, thus forming the Blue Lagoon. After some brave locals found that the mineral-rich waters were good for their skin, it soon became a popular local retreat, and is now one of the best spas in the world. Aside from the therapeutic properties, the milky blue waters in the middle of a lava field (part of the Reykjanes Peninsula UNESCO Geopark) are just aesthetically pleasing - which is probably why everyone from Bjork to Beyonce has been spotted here.
