The Mountains

Croaghaun is a mountain located in Achill Island. At 688 metres, it offers the highest sea cliffs in Ireland as well as the third highest sea cliffs in Europe after Hornelen, Norway and Cape Enniberg, Faroe Islands.

Croaghaun is the most westerly peak of Achill Island. Its cliffs lie on the northern slope of the mountain. The cliffs at Croaghaun can only be seen by hiking around or to the summit of the mountain, or from the sea. They are part of a sequence of sheer rock faced which start south of Keem Bay and loop around the uninhabited north-west of the island by Achill Head and Saddle Head, and east to Slievemore, occasionally dropping vertically into the waters of the Atlantic.
