In a spectacular journey through the Welsh countryside Griff picks up the staff of the medieval pilgrim to retrace the steps that thousands of worshippers made in medieval times from Holywell to St Davids.
Walking with five other hardy companions, the band rediscovers a once well-trodden route that, passing through remote mountain ranges risked attacks from bandits and many other dangers. Foraging for food and facing fast-flowing rivers Griff and his fellow travellers come face-to-face with the perils of medieval travel. Following the arduous tradition of pilgrimage, walking sometimes in sack cloth and sometimes barefoot, they try to understand the lengths that men and women of the middle ages went to in the name of penitence. Passing through beautiful villages, discovering gems of the medieval world from grand manor houses to ancient churches, encountering miracles and relics, bathing in holy wells and washing feet, Griff and his band explore how the British holiday has its roots in the observance of holy days.
