One of Iceland’s most active geothermal areas, Gunnuhver, is evidence of the heat from the Earth’s interior getting close to the surface. The geothermal activity results in intense steam emissions and bubbling mud pots. The area showcases the geothermal forces that shape Iceland’s unique landscapes.

The most prominent feature of Gunnuhver is its powerful steam vents, which emit columns of steam into the air. These vents are caused by the interaction of water with the hot rock below the Earth’s surface. Bubbling mud pots are another fascinating aspect of Gunnuhver. These are created when hot water mixes with minerals in the ground, creating a mixture of mud that bubbles due to escaping gases.

There are also several hot springs in the Gunnuhver area, where you can observe boiling water emerging from the ground. The water’s temperature can be scalding, so staying on marked paths and designated viewing areas for safety is crucial. All have respect for Iceland’s nature when exploring.
