Shaped like a bent crucifix, Stronsay attracts walkers and cyclists for its lack of serious inclines, and beautiful landscapes over its four curving bays. In the 19th century, Whitehall harbour became one of Scotland’s major herring ports, but then the fisheries collapsed in the 1930s. These days it's very quiet; you can easily spot wildlife, with chubby seals basking on the rocks and a healthy bird population, particularly puffins and other seabirds.
There are good coastal walks and, in the east, the Vat o'Kirbister is a fine example of a gloup (natural arch). At the southern end of the island, you can visit the seal-watch hide on the beach. There’s also a chance to see otters at nearby Loch Lea-shun.
