The most popular mountain on the island, perhaps 100,000 attempt the summit each year. St Patrick offers Holy Water at the trailhead.

Croagh Patrick (Irish: Cruach Phádraig), nicknamed the Reek, is a 764 metres (2,507 ft) tall mountain and an important site of pilgrimage in County Mayo, Republic of Ireland.

It is 8 kilometres (5 mi) from Westport, above the villages of Murrisk and Lecanvey. It is the third highest mountain in County Mayo after Mweelrea and Nephin. On “Reek Sunday“, the last Sunday in July every year, over 15,000 pilgrims climb it (some barefoot) …
Saint Patrick reputedly fasted on the summit of Croagh Patrick for forty days in the fifth century and built a church there. Popular legend says that at the end of Patrick’s 40-day fast, he threw a silver bell down the side of the mountain, knocking the she-demon Corra from the sky and banishing all the snakes from Ireland. …
This small chapel dates back to 1905.

St. Paddy camped here. I left a Summit Stone as a token of respect for his good works.

Because many amateur, under dressed non-hikers make the pilgrimage, there are more incidents on this peak than any other on the Emerald Isle.
I was in good hands, guided by Mike from the Mayo Mountain Rescue Team.

The other big celebrity attraction of the remote, rugged region is John Wayne. He filmed The Quiet Man (1952) here. Cong’s gorgeous Ashford Castle, featured in the film, is the centre of the tourist hub bub.
