If you want to experience the wild side of life, then the northern highlands of Scotland is where you have to be. In this episode, Paul Murton is crossing the country coast to coast, from the remote lighthouse at Tarbat Ness over to the iconic castle of Eilean Donan. Travelling off the beaten track, Paul encounters the beautiful bottlenose dolphins that live in the Cromarty firth and travels by horseback through one of Scotland's most spectacular locations, Glen Affric.
