The pilgrims head into Eryri National Park as the pilgrim path leads the group to one of Wales's most famous natural wonders, Aber Falls.They take a detour to the island of Anglesey, which is rich in pre-Christian history. The pilgrim path then goes right past Yr Wyddfa, or Mount Snowdon, the highest mountain in England and Wales, where the group rise to the challenge and attempt the summit. Along the way, they discuss grief, forgiveness and the overwhelming power of nature.
