Reykjadalur Hot River Hike: Private Day Trip from Reykjavík to Geothermal River Baths
Select participants and date
You step off the van and the valley inhales: steam threads between grass and lava rock, a low river hisses like something alive. A guide points the trail up a gentle rib of heath, and within minutes the city’s hum is gone—replaced by the soft crunch of pumice underfoot and the distant metallic scent of sulfur. This is Reykjadalur, the Steam Valley, and its geothermally warmed river invites hikers to earn a soak.

Adventure Tips
Bring a dry bag for electronics
Steam and sudden showers can soak pockets—use a small dry bag so cameras and phones survive the riverbank.
Test pool temperature before getting in
Temperatures vary; ease in gradually and avoid submerging your head to reduce risk of scalding or cold shock.
Layer for changing conditions
Wind and rain can arrive quickly—pack a waterproof shell and insulating mid-layer even in summer.
Use provided crampons in winter
Trails get icy; accept crampons from your guide and use trekking poles if you have them.
