Lundy (Welsh: Ynys Wair) is the largest island in the Bristol Channel. It lies 12 miles (19 km) off the coast of Devon, England,[3] about a third of the distance across the channel from Devon to South Wales. Lundy gives its name to a British sea area and is one of the islands of England.[4] Lundy has been designated by Natural England as national character area 159, one of England's natural regions.[5]

Lundy is included in the district of Torridge with a resident population of 28 people in 2007; these include a warden, a ranger, an island manager, a farmer, bar and house-keeping staff and volunteers. Most live in and around the village at the south of the island. Most visitors are day-trippers, although there are 23 holiday properties and a camp site for over-night visitors, mostly also around the south of the island.

In a 2005 opinion poll of Radio Times readers, Lundy was named as Britain's tenth greatest natural wonder. The entire island has been designated as a Site of Special Scientific Interest[6] and it was England's first statutory Marine Nature reserve, and the first Marine Conservation Zone,[7] because of its unique flora and fauna.[8] It is managed by the Landmark Trust on behalf of the National Trust.
