Rising off the western seaboard of mainland Scotland are hundreds of islands, hidden worlds. Beginning on Arran, Jonny Muir sets out to explore these places with a single ambition: to reach the faraway St Kilda archipelago, the islands at the edge of the world. On the way he attempts to finds his inner peace on Holy Island, takes part in a punishing foot race across the misty mountains of Jura, confronts the Inaccessible Pinnacle on Skye and walks along the white-sand beach on Berneray that became the face of a Thailand tourism campaign. Island life is not without its hallenges. Man-eating midges live up to their reputation on Rum and a furious Atlantic storm threatens to rip his tent to shreds on Barra with him inside. An intensely personal account of a journey through some of Britain s most extraordinary landscapes, Isles at the Edge of the Sea is a celebration of Scotland s west coast islands.
