Rannoch Moor - around 50 square kilometres of not very much. But this soggy desert is the location that two brave travellers have chosen for their adventure. It's a place that has been referenced in many poems and stories over the years, a bleak and desolate place, dotted with lochans and bogs where lonely travellers perish in the nothingness. Film-maker Andrew O'Donnell and his pal Mark Taylor have made it their mission to cross Rannoch Moor in a Canadian canoe, via the waterways that link Loch Ba, Loch Laidon and onto Loch Rannoch. Their journey starts by the side of the road, dropped off by Andrew’s dad (or as he likes to be called, their 'technical coordinator'). The A82 - not a great place to start a boat journey, but is it really a canoe adventure if you don't spend most of your time carrying the canoe? This is the definition of an off-the-grid adventure, in the nicest possible way. There aren't many people living in this bare and boggy terrain. They hope to make it across this wild territory to Kinloch Rannoch in five days - what's the worst that could happen?
