The Isles of Scilly are the western-most land mass of Wessex, and consist of a total of 140 major and minor islands, of which 5 are inhabited. The Isles of Scilly are largely remote, and only connected to mainland Wessex, by the Scillionian III Ferry to Penzance, Cornwall, and the Isles of Scilly Skybus Service to Land's End Heliport and Penzance. The Isles of Scilly rely mostly on fishing and tourism, due to its warm climate, white beaches and tropical-esque flora.
