Here are some of our top dive sites:
Isle of Man (self-governing)
The Isle of Man is a self-governing island in the Irish Sea with golden beaches, excellent diving and plentiful marine life including seals and basking sharks. There are estimated to be over 1500 shipwrecks in the Isle of Man’s territorial waters and the best diving is found on the south side of the island, including at the Calf of Man Marine Nature Reserve. The Burroo is a popular site at the Calf and lies below a sheer cliff that is home to guillemots and razorbills. This dive site offers a variety of crustaceans, nudibranchs and shoals of pollack. Resident grey seals can also be found at the surface. The tidal range at the island can be up to 8m, making some dives suitable for experienced divers only. However, a highlight of any dive trip during May to July is a day spent with the basking sharks and this is suitable for all abilities. Try Isle of Man Diving Holidays and Discover Diving.
The Farne Islands are split into two outcrops lying off the Northumberland coast and are renowned for their shipwrecks and populations of nesting seabirds; including puffins and terns.
