You should be comfortable walking 6 km over uneven ground with a moderate elevation gain (200–300 m); basic endurance is sufficient.
Steam hovers over a hot river and a private guide leads you up through volcanic gravels to a geothermal bathing spot. This half-day hike from Reykjavik pairs terrain that shifts from meadow to mineral with an alfresco lunch in Steam Valley.
A single plume of steam rises from the valley like a punctuation mark against Iceland’s low, gray sky. The guide checks the group, points down the trail, and the sound of gravel under boots becomes the day’s metronome. Within twenty minutes the city recedes: sheep-dotted pastures give way to a palette of rust and ochre, and the air starts to smell faintly of mineral heat. By the time the valley opens, steam is leaking from fissures, a hot river winds below, and the landscape seems to be breathing.

You’ll want to soak in the hot river; quick-dry materials and a waterproof pack keep wet gear contained.
Trail sections are muddy and uneven; boots with good tread and ankle support make the 200–300 m ascent easier.
Stay on marked paths—ground around vents and mud pots can be fragile and dangerously hot.
Book a morning or late-afternoon tour to avoid midday visits and get softer light for photos.
Reykjadalur’s name and use reflect Iceland’s long relationship with geothermal activity; Hveragerði developed as a center for greenhouse farming powered by underground heat.
Stick to trails and avoid adding soap to pools; geothermal features are fragile and Leave No Trace principles help protect vegetation and hot springs.
Offers stability on gravel, boardwalks, and muddy sections of the trail.
Needed to enjoy the hot river baths; quick-dry fabrics pack down small.
Weather can change fast—bring a breathable shell to stay warm and dry.
