The Cap-Coz mudflat an exceptional natural site

Located at the tip of Cap-Coz, in the Bay of La Forêt, the Cap-Coz mudflat is a remarkable natural site in Fouesnant-les Glénan.

This biodiversity-rich environment is a haven of tranquillity for migratory birds, who find peace and food here thanks to the eelgrass beds. While geese return to our shores every year, red-breasted mergansers and sanderlings can also be seen here. The mudflats can be explored on foot, by kayak or even by paddle, in a protected environment.

A natural heritage to preserve

Classified as a Natura 2000 area, the Cap-Coz mudflat benefits from protection measures designed to preserve its fragile balance. This European recognition underlines the ecological importance of this natural habitat, which is directly linked to the quality of coastal waters, the preservation of biodiversity and the fight against coastal erosion.

A little history the origins

On the Cap-Coz mudflats, water is more than just a feature of the landscape: it’s the key to history. Very early on, the inhabitants took advantage of the rich fish stocks in this area where land and sea meet, building ponds and canals to multiply their treasures.

Aquaculture required the construction of numerous hydraulic structures. The large dyke has changed the dynamics of the currents. By reducing the power of the water flow at Penfoulic, it has helped to stabilise the sandy spit at Cap-Coz and create a mudflat behind it.

A remarkable ecosystem in the heart of South Finistère
The mudflat at Cap-Coz was formed by the tides in the Penfoulic cove. Covered at high tide and uncovered at low tide, it is home to a fauna and flora characteristic of estuarine environments. This environment is a veritable bird sanctuary, popular with nature lovers and photographers alike.

An ideal place for observation and awareness-raising
Accessible all year round, the Cap-Coz mudflat is a natural educational area, ideal for nature walks. A path runs along the edge of the mudflat, offering several viewpoints over the site while respecting the tranquillity of the species. From October to February, the Cap-Coz headland welcomes hundreds of geese: an impressive sight for nature lovers!
