Isle of Man

The Calf of Man is a small island off the southern tip of the Isle of Man offering some of the most spectacular diving in the Irish Sea, with dramatic walls, resident grey seal colonies, and summer visits by basking sharks and sunfish. The island's protected status means marine life is exceptionally abundant, and the combination of wall dives, caves, and open reef suits a wide range of diving styles.

Cathedral Rocks on the Isle of Man is one of the Irish Sea's most dramatic dive sites, featuring enormous natural archways and tunnels packed with jewel anemones, huge sea fans, and plumose anemones in brilliant orange and white. The protected waters of the Isle of Man Marine Nature Reserve support exceptional biodiversity, and the site is accessible to intermediate divers on calm tidal conditions.

Sugar Loaf is an impressive underwater pinnacle off the Isle of Man, swept by strong tidal currents that bring in enormous shoals of pollack, coalfish, and bream alongside huge conger eels lurking in the cracks. The pinnacle's walls are covered in soft corals and anemones, and the current-swept nature of the site means it must be timed carefully at slack water.

Isle of Man Diving is the island's premier dive centre, running BSAC and PADI courses alongside regular guided dives to Cathedral Rocks, Sugar Loaf pinnacle, and the Calf of Man's spectacular walls and caves. The centre provides a warm welcome to visiting divers and has deep local knowledge of the Irish Sea's complex tidal patterns.

Manx Divers is a BSAC-affiliated dive club and charter operation based in Douglas, Isle of Man, offering regular dives to the island's finest sites including the Calf of Man, Cathedral Rocks, and a selection of Irish Sea wrecks. They are well-equipped for technical diving and run trimix fills for deeper exploration of the island's underwater landscape.
