Mývatn: The Diamond of the North.

The massive and powerful Dettifoss waterfall plunging into the Jökulsárgljúfur canyon in North Iceland

Dettifoss

Dettifoss is a colossal force of nature and widely considered the most powerful waterfall in Europe. Dropping 45 meters into the rugged Jökulsárgljúfur canyon, the sheer volume of glacial water from the Vatnajökull glacier creates a thunderous roar and a constant mist that can be seen from miles away. The sediment-rich water gives the falls a dramatic greyish-white hue, contrasting sharply with the dark basalt columns of the surrounding cliffs. As a key highlight of the Diamond Circle, Dettifoss offers a raw, humbling experience of Iceland’s wilderness that feels like a journey back to the dawn of time.

(Back to Overview)

Dettifoss stuns with its enormous width and height, roaring glacial meltwater, and dramatic basalt canyon backdrop, creating one of the most powerful and visually striking waterfalls in Europe.

Accessible via paved Route 862 on the west side suitable for all vehicles year-round, and rougher Route 864 on the east requiring 4×4 vehicles and summer access only. Facilities include viewpoints and hiking trails.

Parking is free.

While a popular attraction on the Diamond Circle route, Dettifoss’s remote location and multiple access points help disperse visitors, maintaining a raw and wild atmosphere even during peak tourist seasons.
