On the west coast of Scotland are a group of islands that are so remote they almost seem to have been forgotten by the rest of the world and are populated by just a few hardy souls. Crossing the Sea of the Hebrides, Paul sets off to explore the Shiants, heads east to the romantic Isle of Ewe, and onto the Summer Isles, before travelling to the mighty cliffs of Handa. This tour sees Paul go diving at Scotland's first 'scallop ranch', kayak to the Summer Isles and visit the eerie but beautiful Island of Gruinard, which was once considered to be so solitary and remote it was chosen to be the testing ground for Britain's biological warfare experiments during World War II.
