*Dettifoss is Iceland's greatest and most majestic waterfall. It is also rated as Europe's most powerful waterfall, based on its magnitude. Dettifoss is 45 metres in height and 100 metres wide and its force is such that the bedrock trembles when hit by the weight of an immense column of white-foaming water. The average flow is 193 cubic metres per second but during floods it reaches up to 600 m3/s.
*Dettifoss is in the glacial river Jökulsá á Fjöllum, which emerges from beneath Vatnajökull glacier and runs into Öxarfjörður bay. It is part of Vatnajökull National Park. Dettifoss is the centre fall in a unique series of waterfalls; about one km up river is Selfoss, and two km down river is Hafragilsfoss.
*Dettifoss cuts the river at an angle so the scenic experience is quite different depending on which side the waterfall is viewed from.
*The East Bank Of Dettifoss:
On the east side of Jökulsá river, road 864 runs between road 85 in Öxarfjörður region and main road 1 in the Mývatn area. Despite being a gravel road, it has usually been better than the road on the on the west side, so this is where most visitors come to Dettifoss.
*The West Bank Of Dettifoss:
Road F862 runs between road 85 and road 1 on the west side of Jökulsá river. Between road 85 and Dettifoss it is a gravel road, but between Dettifoss and Road 1 it is more of a mountain track and conditions can vary greatly. A new road is under construction, scheduled to be completed in 2010
