Welcome to the Blue Lagoon! This is the name of the now famous spa resort in south-western Iceland. Its waters come from the Svartsengi geothermal power plant which, thanks to a drill at more than 2000 meters deep, draws water under pressure (12 bar) at 240°C heated by volcanic activity on the island. This water then supply the turbines and produces electricity in addition to heat the towns of Grindavik and Reykjavik, nothing less! Once used, the spring water rich in silica is ejected from the plant at a temperature between 30 and 39°C and goes directly into the spa and the artificial lake of over 200 meters in length located in the heart of a volcanic area, surrounded by lava fields and lichen.
This water is naturally rich in minerals, silicates and blue-green algae, and it is these last that give the lagoon its milky turquoise-blue color and his nickname. Water has healing properties with regard to certain skin diseases such as psoriasis and eczema. A clinic to treat some of these dermatoses opened in June 2005 here and an enlargement of the site is currently underway (2015). This should allow the lagoon to expand and to add different spa facilities and a hotel. The completion is scheduled for 2017.
Thanks to its location, the Blue Lagoon is a must-do activity for tourists, even if they usually stop here on the way back to the airport before leaving Iceland, but it is not our case. The first impression upon arrival is strange: we are facing a great modern looking complex located in the middle of a lava field where nothing grows except foam. We arrive on the huge parking lot, but instead of following the flow of tourists heading straight to the entrance of the spa, we follow a path among the rocks and bordered by small pools.
We finally arrive to the famous artificial lake and perceive the geothermal power plant in the distance. The color of the water is quite beautiful and we can clearly see now all its mineral content. This milky appearance is also found in the waters of the spa. About this, it is time to head to the entrance, as the buses of tourists that we’ve seen earlier in the parking lot must have already invested the premises! We continue our journey along the lake and eventually enter the complex.
