The Isle of May is located in the north of the outer Firth of Forth, approximately 8 km off the coast of mainland Scotland. It is about 1.5 kilometres long and 0.5 kilometres wide. The island is owned and managed by NatureScot as a national nature reserve. There are now no permanent residents, but the island was the site of St Adrian's Priory during the Middle Ages.
Most visitors to the island are daytrippers taking the ferry from Anstruther in Fife, although up to six visitors can stay at the bird observatory, usually for a week at a time. The only way to get there is by ferry; the journey takes 45 minutes from the small harbours of Anstruther and Crail, and also from North Berwick.
