Plage des Granges

Plage des Granges sits at the entrance of the Vilaine estuary and features a blend of coarse sand mixed with scattered pebbles throughout. The approximately 300-meter coastline creates a natural transition between the sandy shore and the river mouth.

The beach lies between two ancient megalithic structures: the Dolmen du Crapaud on the left and the Cairn des Grays on the right. These prehistoric monuments reveal how long people have lived and gathered along this coastal area.

The GR349 hiking trail runs through this beach and connects it to other walking routes along the coast. For hikers, this spot serves as a natural stopping point when exploring the shoreline on foot.

The beach offers free parking, showers, restrooms, and a boat ramp designed for visitors with reduced mobility. The accessible entry points and basic facilities make it welcoming for different types of visitors.

A specially designed walkway lets visitors wade several meters into the estuary waters for direct contact with the waves. This unusual feature creates an immediate experience of the river-to-sea transition.
