Iceland: Asbyrgi Canyon

Asbyrgi Canyon is a national park protection a 3.5 km long and 1 km wine glacial canyon that is almost perfectly horseshoe-shaped depression surrounded with vertical walls. You can drive into the canyon and hike in a beautiful green forest of birch and willow (not a common sight in Iceland), full of wildflowers and birds and stunning panoramic views. The trails lead to overlooks at the edges of the horseshoe and close to the walls, the latter rising absolutely vertically 100 m (330 ft) in height.
