Guide

Approach and anchoring

Approach requires careful navigation among the rocks and islets of Chausey, which show the largest tidal range in Europe with over 14 m at springs. Use the SHOM 7134 chart. Sand and mud bottom offers fair holding. About 1.5 metres of water is left in the pools between the islets at low water, so only shallow craft stay afloat. Exposed to winds from the east and south-east sectors. Tidal streams run strongly between the islets.

Practical

No facilities. Grande Île de Chausey has a restaurant, small shop and the Hôtel du Fort et des Îles open in season. Port de Hérel in Granville lies 8.5 nm east with a full service marina, lock access near high water, fuel and 1000 berths.

Ashore

Grande Île de Chausey can be reached by tender. Footpath circuit of the island takes about 2 hours, passing the lighthouse, the old Fort and the Sound seal haul-outs. The archipelago is a Natura 2000 site and a classified natural reserve for seabirds.
