WHY IS IT BLUE?
The geothermal water has a unique composition, featuring three active ingredients – Silica, Algae & Minerals.

The blue colour 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 colour. The sun simply makes it look blue!
