Gasker Island, located in the Outer Hebrides, is a stunning uninhabited island with a rugged coastline and fertile grassland. The island, which spans approximately 65.6 acres, is home to a grey seal breeding colony and is designated as a Site of Special Scientific Interest (SSSI) for this species. A small, unmanned lighthouse stands on the island, owned by the Northern Lighthouse Board, which is visited periodically for maintenance. The island has two sheltered bays where it's possible to land a small craft, but there are no moorings or buildings currently present. While there are no service connections, it may be possible to construct a small cabin or hut on the island with the necessary consent.
