Silicon dioxide gives the water a bluish tint, and the suspension of mineral clay gives a matte white. In the lake, unicellular blue-green algae actively reproduce.
Until the 80s, when the locals began to swim here, the pond had a purely technical purpose. The geothermal power plant used the hot spring water for the benefit of the inhabitants of the island. But in the early 90s, the healing properties of water began to be noticed, and Dr. Grimoire Samundsen began to study them. Soon, a cosmetic line based on algae, white clay and silicon dioxide was launched in the country. These cosmetics can still be purchased in the spa shop. In 1999, a health center was opened on the shore of the lake, and 6 years later - a clinic for the treatment of skin diseases.
The full-fledged Blue Lagoon resort in its current form was established in 2018. It consists of two hotel complexes, two restaurants, one of which is included in the Michelin Guide, an underground spa complex with saunas. There is also a bar located right in the pool and a small waterfall.
