Stretching the entire western side of Inis Mor Island with views of the Cliffs of Moher, are dramatic and beautiful cliffs with spectacular views. This 8km stretch is known as the Cliffs of Aran and there is infact a trail which takes you from the bottom to the top of the island and takes 2-4 hours to complete. The most frequented area of cliffs by visitors to the island is the fort of Dun Aonghasa. If you venture north, or south for that matter, you are likely to see longer and higher stretches of cliffs with meandering views. You also can very easily find isolation and tranquility.
Dún Dúchathair ( the Black fort) set on the Cliffs of Aran
This fort is situated on the cliffs at Cill Éinne, (Killeany )Inis Mór. Some visitors enjoy the solitude of it in contrast with the busyness of Dún Aonghasa. The fort consists of a terraced wall surrounding the remains of some early dwelling houses known as Clocháns( stone houses). Excavations have not been out carrcled yet so exact dates cannot be given but it is thought to be possibly contemporary with Dún Aonghasa. It is understood that the name the Black Fort comes from the dark coloured limestone which is characteristic of this particular area on the island.
