The Blue Lagoon is a unique wonder of Iceland, a result of all that volcanic activity the small island is so famous for. In the middle of the weird and wonderful, flat black lava fields of the Svartsengi National Park, the huge, outdoor lagoon is filled by naturally heated geothermal water which comes from 6,500 feet (2,000 meters) below the surface of the earth. It is full of minerals, silica and algae and is especially good for the skin and relaxation. In fact, part of the Blue Lagoon development is a health clinic specializing in cures for psoriasis. The water is almost startlingly blue in color, and the white of the silica on the black lava rocks around the edges makes an amazing contrast.
As well as soaking and swimming in the pool, the Blue Lagoon offers in-water massage treatments, saunas and steam rooms, and a cafe. On any visit to Iceland a few hours soaking in The Blue Lagoon is essential, and its location between Reykjavik and the airport makes it easy to do.
The Blue Lagoon is just off the one main road which links the city of Reykjavik and the airport. From the main bus terminal, regular buses go to the lagoon and back daily. The airport bus makes regular stops at the lagoon making the lagoon the perfect first or last stop on your itinerary. From the city to the lagoon takes about 40 minutes, from the lagoon to the airport takes about 20.
