As the second most powerful waterfall in Europe, Dettifoss offers spectacular and breathtaking views. It will not let you down! Keep reading to learn more about Dettifoss waterfall, how and when to visit it, and local tips to make the most out of your trip to North Iceland.

In 2026, the Rhine Falls in Switzerland is widely cited as the most powerful by volume, leaving Dettifoss in Iceland as the second most powerful waterfall in Europe. Located in Vatnajökull National Park, Dettifoss is 100 meters wide and has a drop of 44 meters. Its power comes from its massive discharge: an average of 193 cubic meters per second, which can swell to over 500 cubic meters per second during the peak summer glacial melt. The water is a sediment-rich greyish-white, thundering into the Jökulsárgljúfur canyon with such force that the ground literally vibrates beneath your feet. While some debate exists because "power" can be measured by height or volume, Dettifoss’s sheer mass of water makes it the undisputed heavyweight of the North. Visitors in 2026 can access the falls via Route 862 (West Bank) for a modern paved experience or Route 864 (East Bank) for a more rugged, mist-heavy view of this geological giant.
