This is one of the most southerly of the major islands of the Orkney archipelago in northern Scotland. The site covers the northern and western two-thirds of the island. The cliffs here provide important breeding sites for a number of seabird species, especially gulls and auks, whilst moorland areas support large numbers of breeding birds, in particular great skuas. Red-throated Divers nest here too.
