Linga is made up of sandstone, subjected to ancient glacial erosion.The Holm of Breibister is to the west, the Baa of Linga to the south (baa is a Shetland word for a sunken rock) and the village of Walls is in the North, on the mainland.[2] The surface area is about 65 acres (20 hectares) and there are two derelict cottages on Linga.[2] The local council granted planning permission in 2011 to an oil industry engineer to develop the island[3] but by 2018 these plans had not come to fruition.[1][5] A dead killer whale was found on a beach on Linga in 2017.
