Praying barefoot, rain, hail or shine. Fasting for three days. It can only be the Lough Derg Pilgrimage.
St Patrick's Purgatory, Lough Derg, boasts breathtaking scenery and magnificent buildings.
However, I'm not on this secluded Donegal island for the views.
I'm on a mission - to pray barefoot and fast for three days.
