About
The Mousterlin area has a unique position on the Fouesnant-les Glénan coast. The point lies between the Mer Blanche lagoon to the west and the Mousterlin polder to the east, with beaches stretching over several access points and surroundings rich in dunes, marshes, foreshore and seasonal moorings. In 2026, Fouesnant’s lifeguarded beaches were Cap-Coz, Kerambigorn, Maner Coat Clevarec and Kerler. Mousterlin is not on that list, so swimming there should be considered unsupervised. The town does not install showers on its beaches, to save fresh water. Dogs and horses are banned from 1 June to 30 September. There are many car parks, including several disabled spaces spread across the different Mousterlin access points, and the GR34 runs along the coast. It is an ideal beach for a day of careful swimming, walking, cycling, nature watching and discovering the landscapes of the Mer Blanche.
