In this first 'Grand Tours of the Scottish Islands', Paul Murton sets out to visit some of the myriad of islands that lay off our coastline. Heading to Foula and Fair Isle - the most remote island communities in Britain - Paul makes a nerve-wracking visit to 'Da Snekk o' da Smallie' - a pothole in the cliffs of Foula which leads through to the Atlantic shore on the island, and learns about the beautiful knitting patterns which have made Fair Isle world famous.
