Great Dímon has a sister mountain called Little Dímon. The name is thought to come from Latin, meaning twin mountains or two alike. It has also been said that the word means haystack and it certainly is reminiscent of a haystack surrounded by golden fields. Near the mountain a sign has been erected which tells of battles fought in the area during the times of the settlement of Iceland, in the most famous of Icelandic sagas, Njálssaga. The mountain is only 178 meters high and is a fun hike for both adults and children.
