Iceland is fascinating in countless ways, and its magical Blue Lagoon is no exception. Named because of the startling blue color of its water, this lagoon is fed by runoff water from a nearby geothermal plant, and its waters are as healing as they are luminous. This gorgeous spa is visited by millions of people every year, and we can imagine that it must be very difficult for any bather to get out of the water, which remains at a steamy 98-104F (37-40C) year-round.
The water appears blue because of the high concentrations of silica, algae, and minerals within it. Although the water itself is actually a milky white hue, the silica within it reflects sunlight and the algae adds a bit of green pigment. Although the other, natural geothermal pools around Iceland are also rich in minerals, the unique mineral ratio in The Blue Lagoon has remarkable healing properties, and many people with skin problems such as psoriasis and eczema have noticed a marked improvement after bathing in it!
The beauty of this stunning blue lagoon is matched by the geothermal energy being produced, as harnessing it has allowed Iceland to veer away from fossil fuels in order to heat and power their homes. Using the natural geothermal energy to create electricity is a technique that’s growing by the day—in 2011 alone, nearly 66 percent of Iceland’s energy came from geothermal resources.
