Dursey Island (Irish: Baoi Bhéarra or Oileán Baoi) lies at the southwestern tip of the Beara Peninsula in the west of County Cork in Ireland. Dursey Island is 6.5 km long and 1.5 km wide. The island is separated from the mainland by a narrow stretch of water called Dursey Sound which has a very strong tidal race, with the submerged Flag Rock close to the centre of the channel. The island has just six or so permanent wintertime residents, and is connected to the mainland by Ireland's only cable car.
