The Blue Lagoon is one of Iceland’s most iconic destinations and a must-visit for anyone traveling to the country. Known for its warm, mineral-rich waters and healing silica mud, the lagoon has been a place of relaxation and skin care since 1976. Over the years, it has become world-famous for its unique setting and signature spa treatments, including in-water floating massages.
The geothermal seawater in the Blue Lagoon comes from 2,000 meters below the earth’s surface, where freshwater and seawater meet under high pressure and temperature. It is drawn up through wells at the nearby Svartsengi geothermal power plant, where it is used to produce electricity and hot water for surrounding communities.
As the water makes its way to the surface, it picks up natural silica and minerals. By the time it reaches the lagoon, it has cooled to a comfortable 38°C (100°F)—ideal for soaking, relaxing, and restoring body and mind. The Blue Lagoon’s distinctive milky-blue color comes from the silica, which also plays a key role in its skin-nourishing properties. This unique blend has led National Geographic to name the Blue Lagoon one of its “25 Wonders of the World.”
Silica is not harmful to hair, but it can leave it feeling stiff and difficult to manage once dry. To protect your hair, it is recommended to apply conditioner before entering the lagoon and leave it in while bathing. Complimentary conditioner is available in the shower area.
Whether visiting for a few hours or a full day, the Blue Lagoon offers a one-of-a-kind experience that combines nature, wellness, and Iceland’s remarkable geothermal energy.
