Hike overview
Discover Reykjadalur, meaning "Valley of Steam" in Icelandic, located in the Hengill volcanic region. Although Mount Hengill last erupted 2,000 years ago, the volcano is still active today. The area is dotted with hot springs, bubbling mud pools, fumaroles, and most notably, a geothermal river in which you can bathe.
The site is remarkably well developed: wooden pontoons run along the river for several hundred meters and basic changing rooms are available. The area is organized into small independent natural pools, bordered by stacked rocks, offering a truly unique experience. An interesting detail: the further up the stream you go, the higher the temperature rises, allowing everyone to find their ideal bathing temperature.
