Up to 5,000 people are expected to climb Croagh Patrick today for the annual Reek Sunday pilgrimage.
Archbishop of Armagh and Primate of All Ireland Eamon Martin will take part in the climb and celebrate mass with participants at 11am.
Westport Administrator Father Charlie McDonnell said measures have been taken to make the pilgrimage safer.
“The path is almost completed,” he said. “It's only just 100 metres left now at the very top.
“Pilgrims who are climbing here will realise how much easier it is and safer it is to climb.”
Reek Sunday is held in honor of St Patrick, who is said to have spent 40 days fasting on Croagh Patrick in the 5th century.
This year is dedicated to the vocation to the priesthood.
A special stand is in place at the base of Croagh Patrick for Reek Sunday to raise awareness of vocations and offer information on the priesthood.
