Dova Haw, also known as Crab Island, is a small islet that is one of the Islands of Furness. It is a small tidal island off the coast of Cumbria, England, 0.3 miles (0.48 km) from Barrow Island and 0.6 miles (0.97 km) from Walney Island, adjacent to the town of Barrow-in-Furness. Previously, Dova Haw was the site of an oil lamp lighthouse built from stone, whose foundations are still visible.
