The Blue Lagoon is one of those tourist hot spots that are absolutely worth being a tourist for. Going there straight from the airport offers another benefit; you get to soak away the aches and pains in a delightful setting. Visiting during a windblown snow/sleet mix, it proved a surreal and wonderful experience.
The lagoon itself is fed from the water from a geothermal plant nearby, which produces electricity for the area and hot water for the lagoon. This makes it a highly profitable place indeed. With biting cold wind making us wonder what we were getting ourselves into, the reservation was pleasantly validated as we stepping into the water. This was a place you want to linger in, especially in winter.
They tell us there are many health benefits to immersing yourself in the waters of the Blue Lagoon, largely derived from the briny water, some beneficial algae and an abundance of silica, which turned everything a milky white. After a few hours in the water, I certainly felt the difference on my skin, but also in my overall mood. This place has magical powers. Visit if you go, but be sure to make a reservation well before you go.
