Gunnuhver is a highly active geothermal area of mud pools and steam vents on the southwest part of the Reykjanes Peninsula. Named after an angry female ghost, Gudrun, whose spirit was trapped in the hot springs by a priest 400 years ago. The steamy area has an eerie atmosphere and an incredible sulfur vapor.
A unique characteristic of the Gunnuhver hot springs is that the groundwater here is 100% seawater, unlike other geothermal areas on the island. The colorful minerals in the ground provide vibrant hues, but danger is very real with temperatures over 300°C (570°F) so it is important to tread lightly and stick to the trails. Iceland´s largest mud pool resides at Gunnuhver; it is 20 meters (65 ft) wide of violently boiling earth.
How to get to Gunnuhver thermal springs
Gunnuhver is close to the so-called “toe” of Reykjanes, not far from where Reykjanes lighthouse stands and the roaring waves hit the dramatic sea cliffs. It is a part of the Reykjanes UNESCO Geopark, where you find other attractions such as the geothermal area Krysuvik, ‘The Bridge Between Continents’ and the amazing Blue Lagoon. A guided tour around the peninsula will automatically take you there, and is highly recommended.
