Lundy Island is a boat-access marine reserve with a wide spread of dive options, from shallow seal water to wrecks, reefs, drop-offs, and pinnacles. The island sits in cool, clear water influenced by the Gulf Stream, so it is known for unusually rich marine life for this part of the UK. Divers come here for the combination of protected habitat, varied terrain, and the chance of big marine encounters as well as classic cold-water wreck and reef diving.

Scuba Diving
Over 40 sites are described, including wrecks, reefs, drop-offs, and pinnacles, so scuba options range from easy wildlife dives to more involved wreck visits.
Freediving
Freediving is most realistic in sheltered coves and seal-water sessions on calm days, but tide windows still control the usable time.
Snorkeling
Snorkeling with the seals is a major draw on calm days, especially for mixed groups that want an above-water option.
