The plight of the homeless will be highlighted by 10 pilgrims during a charity walk this Sunday.
Funds to feed Dublin's most vulnerable will also be collected during the eighth annual walk in aid of the Capuchin Day Centre.
The centre provides 2,100 hot dinners, 1,000 food parcels, and 900 breakfasts or lunches each week - costing 50,000 euro a month.
But this time volunteers and staff will rely on the kindness of others for drinks, snacks and encouragement as they make their way from Glendalough to Dublin.
Staff member Paddy Pender said: "The purpose of the walk is to raise awareness about the problem of homelessness in Ireland.
"It is hard to believe that such a service as this is still essential in the 21st century, but the numbers attending for help are increasing at a phenomenal rate since the start of the financial crisis."
For over thirty years the Capuchin Day Centre, run by the Irish Capuchin Franciscan Order, has cared for the capital's homeless.
Ms Pender said many users had jobs when they first came to Dublin.
"The clients come from every part of Ireland, and further afield. No one is too young or too old to find themselves without a home," she added.
The group will leave the Sally Gap at 1pm and arrive at the Capuchin Friary, Church Street, Dublin, for a Gospel Mass at 7pm.
