Hike to Reykjadalur Hot River in Hveragerði

Nestled near the charming town of Hveragerði, the Reykjadalur Hot River hike promises a delightful adventure through Iceland's picturesque landscapes. A relatively short 1-hour trek leads you to the extraordinary Hot River, where geothermal waters invite you to a unique and relaxing experience.

The journey commences at the trailhead conveniently located near the Hot River cafe. The well-defined trail spans 3.88 km, boasting a moderate incline throughout. Allocate around one to one and a half hours for the one-way trip, ensuring you have ample time to relish the surroundings.

The Steam Valley:

As you make your way along the path, the Hot River unveils itself approximately three-quarters into the hike. Opt for an early swim, although the water may not be warm yet. The trail showcases geothermal water holes, a testament to the Earth's powerful forces beneath. Be cautious not to touch the water, given its potential boiling temperatures.


Throughout the hike, treat your senses to the breathtaking views of Iceland's natural wonders. Wooden docks and semi-private changing stalls welcome you at the destination, providing a comfortable spot to prepare for a dip. The water temperature varies upstream, offering options for every preference.

While the trail can attract fellow adventurers, an early start, around 7:30 am, offers a quieter and more serene experience. The crystal-clear water of the Hot River beckons, inviting you to unwind after the invigorating hike. Immerse yourself in the allure of Iceland's geothermal wonders, making the Reykjadalur Hot River hike an essential addition to your Icelandic adventure.
