Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the most powerful waterfall in Europe.
It 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 Europe in terms of volume discharge, having an average water flow of 193 m3/s.
The waterfall can be reached by a new tarmac road, finished in 2011. 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.
Dettifoss is located on the Diamond Circle, a popular tourist route around Húsavík and Lake Mývatn in North Iceland.
Iceland i/ˈaɪslənd/ (Icelandic: Ísland, IPA: [ˈislant]) is a Nordic European island country situated at the confluence of the North Atlantic and Arctic Oceans, on the Mid-Atlantic Ridge. The country has a population of about 320,000 and a total area of 103,000 km2 (40,000 sq mi), which makes it the most sparsely populated country in Europe. The capital and largest city is Reykjavík, with the surrounding areas in the southwestern region of the country being home to two-thirds of the country's population. The nation's capital is the most northern capital in the world. Iceland is volcanically and geologically active. The interior consists mainly of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate despite a high latitude just outside the Arctic Circle.
A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
