Dettifoss, Iceland

Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the most powerful waterfall in Europe.

Dettifoss is situated on the Jökulsá á Fjöllum river, which flows from the Vatnajökull glacier and collects water from a large area in Northeast Iceland. The falls are 100 metres (330 ft) wide and have a drop of 45 metres (150 ft) down to the Jökulsárgljúfur canyon. It is the largest waterfall in Iceland in terms of volume discharge, having an average water flow of 193 m3/s.




Dettifoss can be reached by a new tarmac road (Route 862, finished in 2011) and an older gravel road (Route 864). On the west bank there are no facilities and the view on the waterfall is somewhat hindered by the waterfall's spray. On the east bank there is an information panel maintained by the staff of Vatnajökull National Park (Vatnajökulsþjóðgarður) and a maintained track to the best viewpoints, as well as public restroom.

Dettifoss is located on the Diamond Circle, a popular tourist route around Húsavík and Lake Mývatn in North Iceland.
