Þjófafoss

Wish list
I've seen it

Þjófafoss is a powerful waterfall in the river Þjórsá, located east of the Merkuhraun lava field in South Iceland. The waterfall cascades in a wide flow over dark volcanic rock, clearly demonstrating the immense force of Þjórsá, one of Iceland’s most voluminous rivers. Rising above the area is Búrfell, a volcanic mountain that dominates the surrounding landscape.

Access to Þjófafoss is via a gravel road that is generally passable for all vehicles during the summer months. Nearby is Hjálparfoss, another scenic waterfall in Þjórsárdalur, as well as Fossabrekkur, where visitors can enjoy views over the river and its waterfalls.

Close to Þjófafoss lies Gjáin, a lush green oasis known for its small streams, waterfalls, and striking basalt formations, including Gjárfoss. The area offers a variety of walking opportunities and showcases the remarkable contrast between fertile vegetation and rugged volcanic terrain.

The surrounding landscape has been shaped by volcanic eruptions, lava flows, and powerful rivers over thousands of years. The volcano Hekla looms in the distance and has played a major role in shaping both the physical environment and the human history of the region. Also nearby is Háifoss, one of Iceland’s tallest waterfalls, making the area exceptionally rich in natural attractions.

Visitors wishing to stay longer in the area will find nearby facilities such as the Leirubakki campsite and accommodation options including Afternoon Cottages. Þjófafoss is therefore part of a broader network of natural sights and outdoor experiences within Þjórsárdalur, offering a memorable stop for travelers exploring South Iceland.
