The area sits on one of Iceland's most intense geothermal systems. Mountains reach 1,477 meters and the range is one of the few places in Iceland where snow-capped peaks, colorful rhyolite hills and steaming vents all exist in one view.

Folklore

Story & Folklore

Kerlingarfjöll — 'Old Woman's Mountains' — is one of Iceland's most spectacular and least-visited highland areas. Rhyolite mountains stained in vivid shades of orange, red, yellow and green rise around a geothermal valley where hot springs steam from the ground and colourful mineral deposits festoon the hillsides. The hiking here is among the best in Iceland — varied, dramatic and almost completely crowd-free. The central valley called Hveradalir is the key destination: a surreal landscape of multi-coloured mountains, steaming vents and hot streams where you can bathe in natural pools. Kerlingarfjöll requires a 4×4 or the daily summer bus service from Reykjavík.
