It is part of the Bailiwick of Guernsey, a British Crown dependency. It is 3 miles (4.8 km) long and 1.5 miles (2.4 km) wide. The area is 3 square miles (7.8 km2), making it the third-largest island of the Channel Islands, and the second largest in the Bailiwick. It is around 10 miles (16 km) to the west of La Hague on the Cotentin Peninsula, Normandy, in France, 20 miles (32 km) to the north-east of Guernsey and 60 miles (97 km) from the south coast of England. It is the closest of the Channel Islands to both France and England. It is separated from Cap de la Hague by the dangerous Race of Alderney (Le Raz Blanchard).
