The heavy volcanic activity in the region surrounding Lake Myvatn over the last few thousand years accounts for extraordinary and sometimes eerily beautiful land formations and geology. Dimmuborgir, on the east side of the lake, are a badlands of lava pillars, caves rugged crags and towering rocks, some of which reach 20 meters (65 ft) in height.

Dimmuborgir, which loosely translated means ‘dark castles,’ are thought to have been created about 2,300 years ago in the violent throes of an extensive volcanic eruption.

There are three different routes marked for walking in the labyrinth of ethereal lava formations which provide shelter for unexpectedly rich vegetation during summer. During winter the caves provide temporary shelter for the Yule Lads who make them their home around Christmas time.
