Mary-Ann Ochota joins a group of walkers, riders and horses as in the Scottish Highlands as they follow St Columba’s Way, a pilgrim route from St Andrew’s to Iona. Starting at the village of Killin, eleven people and four horses – Istia, Kirsty, Moy and Sasha - follow the old ways through Glen Lochay and Glen Lyon to the Bridge of Orchy. It's a trip organised by The Big Hoof, a group which promotes adventure and wellbeing through long journeys travelling with horses, on both new routes and ancient ones. Participants join the journey for as long as they want - on foot, horseback or bicycle. Mary-Ann meets the people who have decided to take part in this secular pilgrimage, discovers the healing power of walking with horses and strangers, learns why it’s not about simply riding horses but travelling with them as companions, and hears more about the Venture Trust, the charity the group is raising money for. Produced and presented by Mary-Ann Ochota
