Baie de Vilaine
A range of coastal habitats can be explored in this estuary on the south coast of Brittany to the south-east of the Golfe du Morbihan. There are sandy, shingle and rocky beaches, extensive inter-tidal mudflats, saltmarsh and cliffs.
The area is important for tens of thousands of waders, waterfowl and seabirds in autumn and winter.
