Reykjadalur — “Steam Valley” in Icelandic — has earned its reputation as one of the country’s favourite geothermal hikes. Just outside Hveragerði, the trail rewards you with rolling, sulphur-tinged scenery and, at the end of it all, a long soak in a naturally warm river.
Route Overview
The trail runs about 6 km round trip through the Hengill geothermal area, following a well-maintained path the whole way. Expect a solid uphill push at the start — it eases off once you gain the ridge.
Terrain and Scenery
Gravel paths wind past steaming vents, bubbling mud pools, and vivid mineral deposits staining the ground in oranges and yellows. Partway along, Djúpagilsfoss waterfall appears on the right — worth a pause before you push on to the river.
