Þjórsárdalur

Þjórsárdalur (the valley of Iceland’s longest river, the Þjórsá) is one of the most historically and scenically rich valleys in Iceland. Norse settlers farmed here until the 1104 eruption of Hekla buried the landscape in ash; the reconstructed Viking longhouse at Stöng offers a vivid window into that world.

Beyond its history, the valley is a gateway to several spectacular natural attractions — Háifoss, Hjálparfoss, and the hidden canyon of Gjáin are all within easy driving distance of each other along Route 32. The surrounding hills offer open hiking and views toward the Hekla volcano.

The valley is accessible year-round on the paved lower section of Route 32, though inner roads to the waterfall car parks become rough gravel. Allow a full day to explore the main sites. The area is quiet and uncrowded compared to the Golden Circle.
