moderate
2 days (approx. 48 hours)
Light to moderate fitness; able to manage short hikes and mount/exit 4x4 vehicles.
A compact two-day escape into Hengill’s geothermal heart: soak in Reykjadalur’s warm streams, cross rivers and lava fields in a 4x4, tour Hellisheiði power plant, then sleep in a simple mountain hut under wide Icelandic skies. Ideal for travelers who want raw landscape and human-scale comforts in one trip.
The engine coughs, then settles—low and steady—while steam coils from a patch of ground like breath in the cold. You step out and the air is scattered with the metallic tang of sulfur; beneath your boots the earth is warm, and a distant river dares you to follow it. This is Hengill country: a braided landscape of black lava, mineral-streaked hills, and geothermal fissures just a short run from Reykjavik. Over two days the trip folds from short, easy hikes to bolder off-road driving, capped by a night in a remote mountain hut where the wind and stars keep the schedule.

Temperatures can swing quickly between wind, sun and rain—pack a breathable insulating layer and a waterproof shell.
Water temperature varies; check before entering and avoid scalding pools—stick to designated bathing spots.
Expect wet lava rock, muddy trails and river fords—waterproof hiking boots with good tread help prevent slips.
Stay on trails to protect moss and vegetation; off-trail walking can cause irreversible damage.
Hengill’s geothermal fields have long supported local bathing and, more recently, large-scale geothermal energy production centered at Hellisheiði—part of Iceland’s push toward renewable electricity.
Trails and hut areas are managed to protect fragile volcanic moss and geothermal features; visitors should avoid off-trail walking and pack out all waste.
Keeps wind and rain out during exposed drives and hikes.
Protects feet on wet lava, muddy trails, and shallow stream crossings.
For soaking in Reykjadalur’s hot springs—choose quick-dry fabrics.
