Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland. It is part of the Diamond Circle and it is the considered the most powerful waterfall in Europe. The water of the Jökulsá á Fjöllum river descends from the nearby Vatnajökull glacier and falls for more than 44 metres, causing a massive, crashing spray. This the largest waterfall in Iceland in terms of volume discharge.
