Croaghaun

Croaghaun (Irish: Cruachán, meaning "little stack" or "little mountain heap") is a mountain located on Achill Island, County Mayo, Ireland. It is the westernmost point of Achill and one of the highest sea cliffs in Europe.

The mountain reaches a height of 688 metres (2,257 feet). Its western face features dramatic sea cliffs that plunge directly into the Atlantic Ocean. These cliffs are a major tourist attraction and a significant geological feature.

Reaching the summit of Croaghaun requires a challenging hike, often involving traversing boggy ground and steep slopes. There are no maintained trails, and the weather conditions can change rapidly. The views from the summit are extensive, encompassing the entire island of Achill, the coastline of County Mayo, and the surrounding islands.

Croaghaun forms part of the Wild Atlantic Way, a scenic coastal route that stretches along the entire west coast of Ireland. The area surrounding Croaghaun is largely uninhabited and retains a sense of wilderness. The flora and fauna of the mountain and its cliffs are of ecological significance, supporting various bird species and plant life adapted to the harsh coastal environment.

The name "Croaghaun" is also sometimes applied to a townland in the civil parish of Achill.
