39. The Knoydart Peninsula
"Wild camping and strenuous hiking are the best ways to explore this rugged Scottish peninsula," states Sarah. "Knoydart is famously home to the UK's most remote pub, which gets busy despite being accessible only by boat or boots. To get even further from the crowds, Wilderness Scotland's six- or seven-night Wilderness Walking trips around the Knoydart Peninsula take in some of the region's least explored corners."
Details: These trips take place on four dates throughout the summer and cost from £975 per person, including full-board accommodation in a cosy wilderness lodge, guiding and transfers to and from Mallaig (wildernessscotland.com).
