Century-old wrecks and kelp walls in Europe's biggest tides

Chausey is a scatter of small islands, islets and rocks off the Normandy coast, dived by fast RIB out of Granville. The Granville boats work around thirty sites along this stretch of the Channel, from kelp-hung drop-offs to wrecks, some a century old: the Anvers to the east of the islands, open to French Level 1 divers, the Voilier on sand at 38 m south of the Sound, and, out near the Minquiers, the Fetlar between 20 and 30 m. Tides here reach 14 m on the equinoxes, the largest range in Europe, and strong currents run through the islands.

About diving in Chausey Islands & Granville

Diving at Chausey is boat diving from the port of Granville. Plongée Chausey Loisirs runs fast RIBs out to the archipelago and works a pool of around thirty sites, and the Club Subaquatique Hippocampe, a members' club based at Granville, keeps its own site list, from Le Founet and Videcoq to the Anvers wreck. The same stretch of the Emerald Coast runs on from the Bay of Saint-Malo past Chausey to Jersey, with the Minquiers reef at its heart. Night dives are offered as well as day trips. The tide governs the day: the range reaches 14 m at the equinox springs, and currents sweep the islands continuously.

Underwater the archipelago is granite and steel. Drop-offs are hung with laminaria kelp, and wrecks, some of them a century old, lie out in open water. The Anvers sits to the east of the islands and the Voilier rests on sand at 38 m south of the Sound, beside a drop-off; the Fetlar, between 20 and 30 m, lies out near the Minquiers. The fish are pollack, bass, ballan and cuckoo wrasse, mackerel and bream, with cuttlefish, octopus, lobster, spider crabs and crawfish among them. The water is cold, from about 9 °C in February to 19 °C in late August.

The area suits divers already comfortable in cold, moving water and keen on wrecks. French Level 1 divers have the Anvers, while the Fetlar and the Voilier lie between 20 and 38 m. For a British take on Channel wreck diving, with a training shore site in Chesil Cove, Weymouth & Portland lies across the water on the Dorset coast.

Dive types & marine life

Fish life is the draw: pollack, bass, ballan and cuckoo wrasse, mackerel and bream, with cuttlefish, octopus, lobster, spider crabs and crawfish. The strong, constant currents that feed the lobster fishery keep the water well mixed. The archipelago has been a bird protection zone since May 1988.
