Supposedly Europe's most powerful waterfall. With a drop of 44 m and a width of 100 m, it has the second-largest volume discharge in Iceland, only behind Urriðafoss (which is much smaller).
Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the second most powerful waterfall in Europe after the Rhine Falls. 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 sediment-rich runoff colours the water a greyish white.

2.5 kilometres further up the river than Dettifoss, this waterfall is 27 metres high and about 91 metres wide. Access is via a lookout point from the car park (unsealed) or via a trail that allows you to get much closer to the waterfall from Dettifoss (car park is sealed).
A 12-metre-high waterfall further upstream. Easily accessible via a short walk from the car park.
One of the two main highlights of the park features a very unusual and large cliff formation 60 km east of Húsavík, which is said to be the hoofmark of Odin's horse.
