CHAUSEY is a Norman archipelago located off the Mont Saint-Michel Bay, 17km (10.5 miles) off the town of Granville to which it is administratively attached. The archipelago is part of a rectangle, approximately 6.50km (4 miles) wide and 12km (7.4 miles) long, is comprised of 52 small islands at high tide, 365 small islands and thousands of rocks at low tide and has a landscape that is constantly changing due to the 14 metre (49.2 ft.) difference between high and low tide.

This is an archipelago where nature is preserved, with no cars, a few houses including that of the famous Marine painter, "Marin Marie", and magnificent landscapes in the middle of the water!

You will be charmed by some unusual places: the fishing village ("les Blainvillais"), Moines and Eléphant rocks, Port Marie and Port Homard beaches, Renault castle built in 1928, the chapel built in 1840, the lighthouse, the fort with its 15 metre (49 ft.) ditches dug in the granite.

The entire archipelago of Chausey is listed; many birds go there to reproduce, well protected from land predators.

Useful information: the Blainville-Sur-Mer Tourist Office makes reservations (at no extra cost). Dogs on leads are allowed.
