Located in the shadow of the Svartsengi geothermal power station, the steaming waters of the Blue Lagoon have transformed this plant's mineral-rich overspill into one of the most iconic health retreats in the world.

The thermally heated waters of the Lagoon remain at a balmy temperature (37-39°C), regardless of the chilly Icelandic winds, while minerals brought up through lava flows from beneath the earth's crust turn the water a startling shade of pastel blue. These minerals have been found to have remarkable curative properties and are especially beneficial for the skin.

Relax in a hollowed-out lava cave, now a sauna-bath; indulge in VIP treatments at the Lagoon's Exclusive Lounge or visit the spa shop to stock up on products created from the beneficial silica and algae that've made the lagoon such a seductive spa destination.
