St Patrick couldn't have picked a better spot for a pilgrimage than this conical mountain (also known as 'the Reek'). On a clear day, the tough two-hour climb rewards with stunning views over Clew Bay and its sandy islets.
It was on Croagh Patrick that Ireland's patron saint fasted for 40 days and nights, and where he reputedly banished venomous snakes. Climbing the 764m holy mountain is an act of penance for thousands of believers on the last Sunday of July (Reek Sunday). The truly contrite take the ancient 35km pilgrim's route, Tóchar Phádraig (Patrick's Causeway), from Ballintubber Abbey and ascend the mountain barefoot. The 7km trail taken by the less repentant begins at the village of Murrisk.
