Blue Lagoon

The waters of the Blue Lagoon are naturally heated by geothermal heat resulting from the Earth’s volcanic activity on the Reykjanes peninsula.

The nearby geothermal plant extracts super-heated water from the Earth to produce power. After that, the leftover hot water is mixed with sea water and led into the Blue Lagoon to for a comfortable bathing experience.

The water temperature in Iceland’s breathtaking Blue Lagoon varies, but is usually around 38°C (100°F). This may vary slightly depending on the time of year you visit the Blue Lagoon.

The Blue Lagoon is a stunning geothermal spa set the in natural lava fields of the Reykjanes peninsula. The lagoon itself however is man-made, being carved into the local rocks.

The water you’ll bathe in is heated naturally by the geothermal activity beneath the surface of the Earth. It’s these milky blue waters that have made the Blue Lagoon one of the most popular attractions in Iceland.
