Drekagil Canyon
A highlight of the Dyngjufjöll massif that surrounds the Askja caldera, the “Dragon Gorge” is a gnarly canyon that resembles a dragon from certain angles. When the river running through the canyon is shallow enough, a relatively short hike leads to a lovely waterfall. Drekagil is a basecamp for trails leading to Askja, Öskjuvatn, and Víti, with a mountain hut, a rangers' station, and camping facilities. There’s water available, but you’ll need to bring food supplies.
