Ásbyrgi

Asbyrgi is the remarkable horseshoe-shaped canyon which Viking settlers believed to be a hoof-print formed by Sleipnir, Odin’s eight-legged flying horse from Norse mythology. Geologists believe it was formed as the result of a catastrophic flood from the nearby Jokulsa glacial river.

Located in Jokulsargljufur within the Vatnajokull National Park, Asbyrgi has 100 meter (330 ft) high cliffs which form a 1 kilometer (.5 mi) wide ring of protective shelter around the rich vegetation and forest. The forest is a protected area but there is camping near the canyon’s entrance and you can climb the canyon itself.
