description Dettifoss Overview
Grey, sediment-laden water surges over Dettifoss in northeastern Iceland, where the Jökulsá á Fjöllum river descends into the Jökulsárgljúfur canyon. The river is fed by the Vatnajökull ice cap, linking the waterfall to a much larger glacial drainage system. Within Vatnajökull National Park, the broad cataract is known for its forceful flow and the spray rising from the gorge. The appeal lies in the weight and movement of the water against a stark rock setting.
Its flow varies, so a single discharge figure should not be treated as a constant measure of its power. Visitors interested in Iceland's volcanic terrain and glacial rivers can see both influences in the surrounding environment. For researchers studying erosion and river behavior, Dettifoss provides a striking example of a large glacial river cutting through a canyon.
help Dettifoss FAQ
Where is Dettifoss located and what national park is it part of?
Dettifoss is located in northeast Iceland within Vatnajökull National Park, on the Jökulsá á Fjöllum river. It sits roughly 100 kilometers southwest of the town of Húsavík and is accessible via Route 862 during the summer months.
How does Dettifoss compare in power to other European waterfalls?
Dettifoss is considered the most powerful waterfall in Europe by water discharge volume, with an average flow of about 193 cubic meters per second. It has a width of roughly 100 meters and drops 44 meters into the Jökulsárgljúfur canyon.
Has Dettifoss appeared in any films?
Yes, Dettifoss was prominently featured in the 2012 Ridley Scott science fiction film 'Prometheus,' where it served as a primordial Earth landscape in the opening sequence. Its raw, grey, mist-shrouded appearance made it a fitting stand-in for a prehistoric setting.
Are there other notable waterfalls near Dettifoss?
Two other significant waterfalls lie on the same Jökulsá á Fjöllum river: Selfoss, located about one kilometer upstream, and Hafragilsfoss, located downstream. All three are accessible via hiking trails and the gravel roads of the Jökulsárgljúfur canyon area.
