Hiking Trails in the Hengill Area.
Everyone welcome!

The Hengill Area is a high-temperature geothermal area located about 20 kilometers southeast of Reykjavík. Every year, tens of thousands of Icelanders and foreign tourists engage in outdoor activities in the Hengill Area, which features around 110 km of marked hiking trails. Outside of the operational areas of ON Power's power plants, the area is open to the public. The Hengill Area is in an active volcanic zone with hot springs, lava craters, rivers, lakes, and lush green areas.

The Hengill Area is ideal for outdoor activities year-round. Various arrangements have been made for outdoor enthusiasts, including marked hiking trails, information signs, hiking huts, and a hiking trail map. ON Power and formerly Reykjavík Energy have been responsible for this work since 1990, in consultation with local authorities in the area.
