Cameron McNeish celebrates the best of Scotland's history and landscape with a new coast-to-coast walk across the Highlands from Argyll to Easter Ross. This is a journey into a rich and often turbulent past, following in the footsteps of our ancestors, the Celtic priests, Vikings, fugitives, red coat armies, or even those who earned their day-to-day living here, the lead mine workers, deer stalkers, drovers and hydro workers. In the first of two programmes, Cameron walks the first half of this 250-mile route, from Iona, often called the cradle of Christianity in Scotland, to Glen Affric. Taking in Mull's highest mountain, Ben More, he travels through the Morven hills, the atmospheric Sunnart Oakwoods and into the wild and remote landscape of Morar.
