At marvellous Hermaness headland, a 4.5-mile round walk takes you to cliffs where gannets, fulmars and guillemots nest, and numerous puffins frolic. You can also see Scotland's most northerly point, the rocks of Out Stack, and Muckle Flugga, with its lighthouse built by Robert Louis Stevenson's uncle. Duck into the Hermaness Visitor Centre, with its poignant story about one-time resident Albert Ross.
The path to the cliffs is guarded by a squadron of great skuas who nest in the nearby heather, and dive-bomb at will if they feel threatened. They're damn solid birds too, but don't usually make contact.
