Description
The Blue Lagoon geothermal spa is the most visited attraction in Iceland.The spa is located in a lava field in Grindavík on the Reykjanes Peninsula, southwestern Iceland. It is situated approximately 12 mi from the Keflavík International Airport and 24 mi from the capital city of Reykjavík.
The geothermal water originates 2,000 metres below the surface, where freshwater and seawater combine at extreme temperatures. It is then harnessed via drilling holes at a nearby geothermal power plant, Svartsengi, to create electricity and hot water for nearby communities.
On its way to the surface, the water picks up silica and minerals. When the water emerges, its temperature is generally between 37°C and 40°C (98-104°F). But owing to variables outside of our control – including weather and time of year – the water temperature sometimes fluctuates beyond this range.
Why is it blue? The geothermal water has a unique composition, featuring three active ingredients – Silica, Algae & Minerals.
The blue color comes from the silica and the way it reflects sunlight. During summer there can also be a hint of green in the water. This is the result of the algae, which multiplies quickly when exposed to direct sunlight.
However, and this might come as a surprise to you, the water is actually white. If you pour it into a transparent cup, it will always have a milky white color. The sun simply makes it look blue!
