The crater is about 150 m in diameter and 900 m long. It is considered a true underground wonderworld. Here you can clearly see flow lines of the old lava as well as spectacular lava formations such as stalactites and a truly peculiar formation known as the 'chandelier'.
The bones of an Icelandic sheep who´s said to have lived there for centuries have been discovered in the cave, and research says that it may date as far back as the Saga Age.
