Blue Lagoon is one of the most visited lakes in Iceland , on the Reykjanes peninsula. Its thermal waters, rich in minerals such as silica and sulfur, attract thousands of tourists as if it were a natural spa .
It is also reputed to help people with skin conditions such as psoriasis. The water temperature is around 40 ° C throughout the year, even in the middle of winter.
The lagoon has these properties thanks to the water outlet near the Svartsengi geothermal power plant , which works due to the existence of an underground lava flow that serves to move the turbines that generate electricity.
