BLUE LAGOON - ICELAND

This natural phenomenon is one of the most beautiful sites on earth. 
Heavily photographed, this wonder never ceases to amaze and inspire awe. The geothermal water originates 2,000 metres below the surface, where freshwater and seawater combine at extreme temperatures.

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, including weather and time of year, the water temperature sometimes fluctuates beyond this range.

The geothermal water is the most stunning shade of blue and has a unique composition,
featuring three active ingredients – Silica, Algae & Minerals. All with amazing health benefits.

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, the water is actually white. If you pour it into a transparent cup, it will always have a milky white colour.
The sun actually makes it look blue!
