Paul Murton tours Outer Orkney, beginning at North Ronaldsay, which may be the most northerly of the Orkneys but turns out to be surprisingly easy to get to. Paul then hops across to Papa Stronsay, which is now populated by an order of monks who have chosen to make this isolated island their home, and ends on the island of Stroma in the Pentland Firth, a previously inhabited island that was abandoned in the 1950s. One of the last people to live there joins Paul to recall when it was still a thriving community.
