The Marais de Mousterlin, classified as a Natura 2000 site, is located in the commune of Fouesnant, just a stone’s throw from the campsite. Nestled between the Pointe de Mousterlin and the Pointe de Beg Meil, this natural site extends just a few kilometers from the famous Glénan archipelago. The site comprises three distinct areas: La Mer Blanche, the Marais de Mousterlin and the dunes of Cleut Rouz and Kerambigorn.
The Marais de Mousterlin is a must-see destination for nature lovers. The site offers remarkable ecological diversity. The dunes of Cleut Rouz and Kerambigorn, the wet meadows and coastal lagoons form a mosaic of natural habitats where exceptional flora and fauna cohabit.
Rare and protected species can be observed here, such as the Horned Argiope, the Interrupted-Collared Gravelot and the Brent Goose. Birdwatchers will be delighted by the presence of numerous birds such as Kingfisher and Cisticola.
To discover this little natural paradise, follow the marked trails that will take you through the different habitats without disturbing the flora and fauna. The early hours of the morning are ideal for observing nature as it wakes up, while enjoying the peace and quiet of the area. Remember to take binoculars to better appreciate the many bird species present on the site.
To preserve this fragile ecosystem, we advise you to scrupulously respect the rules posted on the information panels. Avoid leaving the trails, take your garbage home with you, and if you are accompanied by a dog, it is compulsory to keep it on a leash.
The Fouesnant tourist office has posted an itinerary on its website. You can view it here.
The Mer Blanche itself is an open-access natural site with no museums, but you can visit the ornithological observatory at Lanrivoal Pez Douar.
The Mousterlin marsh was once directly connected to the ocean. The dikes installed in the early 20th century to drain the land and increase agricultural acreage had cut off this direct communication. Today, an automatic valve allows salt water to be reintroduced, recreating the original lagoon ecosystem. The locality of Vorlen, to the east of the marsh, even takes its name from the Breton word “morlenn”, meaning lagoon.
The upkeep of the marsh is also a story in itself. In an original way, the agricultural management uses a herd of Nantes cows from the Lycée agricole de Bréhoulou for extensive grazing, thus preserving the wet meadows and maintaining an open landscape favorable to certain species.
The entire coastline, from the Mer Blanche to Beg Meil and the Marais de Mousterlin, has been designated a Natura 2000 site. The aim of this European network is to maintain habitats and species important for European biodiversity in a good state of conservation.
By visiting the Marais de Mousterlin, you are also contributing to a conservation effort shared by several local and regional players. Numerous initiatives, such as hydraulic management and the fight against invasive plants, bear witness to the importance attached to preserving this unique natural area.
Don’t wait any longer, come and discover this nugget of Breton biodiversity and immerse yourself in a haven of peace where nature reigns supreme.
