The Isle of Erraid is a tidal island approximately one mile square in area located in the Inner Hebrides of Scotland. It lies west of Mull (to which it is linked by a beach at low tide) and southeast of Iona. The island receives about of rain and 1,350 hours of sunshine annually, making it one of the driest and sunniest places on the western seaboard of Scotland. It is attended by numerous uninhabited small islets, the largest being Eilean Dubh (of which there are two), Eilean nam Muc, Eilean Chalmain, Eilean Ghomain and Eilean na Seamair.
The island features a disused signal station for the lighthouses on Dubh Artach and Skerryvore and a row of cottages built for the lighthouse keepers.
Satish Kumar has also visited the island and his autobiography includes an account of the event.
The island is privately owned and is home to an intentional community, part of the Findhorn Foundation.
There is a well-known anchorage on the western side of the island called 'Tinker's Hole'1. It is a deep but narrow channel between Erraid and the westernmost of the islets called Eilean Dubh.
