Lundy gives its name to one of the British Sea Areas.
As of 2007, there was a resident population of 28 people, including volunteers. These include a warden, island manager, and farmer, as well as bar and house-keeping staff. 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 staying 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 and it was England's first statutory Marine Nature Reserve, because of its unique flora and fauna. It is managed by the Landmark Trust on behalf of the National Trust.
The island is primarily composed of granite from the palaeocene period, with slate at the southern end; the plateau soil is mainly loam, with some peat. Among the igneous dykes cutting the granite are a small number composed of a unique orthophyre. This was given the name Lundyite in 1914, although the term—never precisely defined—has since fallen into disuse.
Lundy has 23 holiday properties to choose from sleeping between 1 and 14 people. These include a lighthouse, a castle and a Victorian mansion. Many of the buildings are constructed from the island's granite. All have heating and many also have wood burning stoves with a bath or shower depending on size. Kitchens are fully equipped for those wishing to self cater.
The island also has a campsite, at the south of the island in the field next to the shop. It has hot and cold running water, with showers and toilets in an adjacent building.
