For this grand tour, Paul's journey begins at Loch Hourn on the mainland, takes him over the sea to Skye and then heads to the tiny island of Soay before finishing on Canna. Along the way, Paul visits the house which was the inspiration for Skyfall, home of Britain's most famous spy James Bond, embarks on a nerve-wracking caving expedition under the summit of Blaven and discovers the remarkable story of shark fishing off Soay.
