A small uninhabited island in the Firth of Forth, Cramond Island lies a mile (1.5 km) north northeast of the village of Cramond, to which it is connected at low tide across the Drum Sands. The island occupies an area of 7.7 ha (19 acres). Like several of the other islands in the Firth, there are several Second World War fortifications on the island and the narrow pier, topped by a line of concrete pyramids, which also connects the island to the shore, was constructed at the same time as an anti-submarine defence. This today runs alongside a sewage outfall.
The island is the property of the Dalmeny Estates.
