ICELAND straddles the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are pulling apart. Upwelling magma built the island and heats its vast reservoirs of water, creating a geothermal paradise. First among the country’s many simmering geothermal pools is the Blue Lagoon, a turquoise vision in a black basaltic moonscape. The geothermal spa is fed by seawater 6,500 feet (1,981 m) beneath the surface, where it reaches a searing 464ᵒF (240ᵒC). capturing silica and other minerals on its way to the surface, it mereges fro mthe ground at a balmy 100ᵒF (38ᵒC), just right for pampering visitors.

BLUE OASIS The Blue Lagoon’s intense colour comes from a combination of blue-green algae and white silica mud. Visitors often rub the chalky mud into their skin, believing it has healthful properties.
