Further inland, along the glacial river that once shaped Ásbyrgi are the canyons through which the mighty river still flows. Among the sights in the area is Dettifoss, the most powerful waterfall in Iceland.

History

Landscape

The area is of interest because of its chaotic canyon and volcanic mountains. Eight thousand years ago, volcanic fissures of the Askja volcanic system erupted directly underneath the river and glacial ice. This caused explosions and chaotic flooding.

The centre of the area is Vesturdalur with Hljóðaklettar (rock of echoes). Rauðhólar (red mountain) is of interest because of its special colouring due to iron oxidations.

Get around

See

  • 🌍 Ásbyrgi, Road 861. 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. 
  • 🌍 Dettifoss, Dettifossvegur vestri (west side), Dettifossvegur eystri (east side) (parking available at both sides of the waterfall). 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). 
  • 🌍 Hafragilsfoss. 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). (updated Mar 2024)
  • 🌍 Réttarfoss, Dettifossvegur (via road 862). A 12-metre-high waterfall further upstream. Easily accessible via a short walk from the car park. (updated Mar 2024)
