See the Isles as few, including its inhabitants, have ever seen them—largely because an expedition ship is required. Tropical gardens on the Isles of Scilly. Beehive huts of 6th century Celtic monks. Cliffs thronged with puffins at St Kilda. Macbeth’s (presumed) grave at Iona. Despite centuries of civilization, there is a pervasive wildness still, and a visible pre-history.
