Hengifoss

Hengifoss is one of the most impressive waterfalls in East Iceland. It is located in the northern part of Fljótsdalur, close to the inner end of Lagarfljót. The waterfall flows in the river Hengifossá and ranks among the highest waterfalls in Iceland.

For many years Hengifoss was believed to be about 118 metres high, but more recent measurements have shown it to be even taller, placing it among the three highest waterfalls in the country. The waterfall is renowned not only for its height, but also for its striking appearance and vividly coloured rock layers in the surrounding canyon.

At the top of the cliff, dark basalt layers rest above red sandstone formations. Within the sandstone, fossilised tree trunks have been discovered, providing evidence of a much warmer climate during the Tertiary period millions of years ago. This remarkable geological history makes Hengifoss one of Iceland’s most significant natural landmarks.

Further downstream lies another waterfall, Litlanesfoss, which plunges into a deep gorge surrounded by spectacular basalt columns. Many visitors consider it among the most beautiful waterfalls in Iceland, despite standing in the shadow of its taller neighbour.

The hike to Hengifoss is popular and easily accessible. A well-marked trail begins at the parking area along Road 931 and takes approximately 1–1.5 hours to reach the waterfall at a relaxed walking pace. Along the way, hikers are rewarded with sweeping views over Fljótsdalur and Lagarfljót, with the waterfall visible from afar as the trail ascends.

Hengifoss offers a rare combination of natural beauty, geological history and accessibility. Here, the power of flowing water, the layered story of the earth and the vast landscapes of East Iceland come together in one of the country’s most unforgettable waterfall scenes.
