of wildlife. Comprising 70 islands, of which just 19 are inhabited, Orkney is extraordinary. The World Heritage Site of Neolithic Orkney harbours many archaeological treasures, including Skara Brae, the most important Stone-Age village in northern Europe, and Maeshowe chambered tomb, whose entrance is aligned with the setting sun on the winter solstice. Here you'll also find the Old Man of Hoy, a spectacular 140m-high sea stack; Scapa Flow, scene of the dramatic scuttling of the German fleet in 1919; and dramatic nature reserves with cliffs upon which one in six UK seabirds nests.
