Just an 18-minute drive from Camping Les Saules, Mousterlin embodies the very best of the Breton coastline: vast ocean beaches, unspoilt dunes, a listed marsh and an atmosphere where nature reclaims its rights. This southernmost tip of Fouesnant is well worth a visit, whether you come for a rejuvenating stroll or a full day of exploration.
The spirit of the place: an area between land and sea
Mousterlin is distinguished by its unique lagoon system, transformed into a protected wetland. Seen from the air, the geography reveals a landscape shaped by the elements: white dunes, verdant marshes and the Atlantic Ocean meet to create a scenery that changes with the tides.
This territory combines two complementary faces: the rocky headland exposed to the onshore winds, and the quiet back dunes where the marsh paths wind their way. This duality makes Mousterlin a privileged site for walkers, nature-watchers and lovers of wide-open spaces.
Must-see attractions
La Pointe de Mousterlin: the area’s signature walk
The walk around the headland is Mousterlin’s signature experience. What’s particularly appealing here is the sense of space and the slightly wild atmosphere that contrasts with the more intimate coves of Beg-Meil.
The route alternates between :
- Passages on firm sand along the beach
- Paths between the dunes with panoramic views
- Observation points off the Glénan archipelago
- Rocky areas where cormorants and gulls nest
Good to know: Sunsets from the point offer a memorable spectacle, with the islands silhouetted against the horizon. To enjoy the sandy expanse to the full, it’s best to go at low tide.
The Mousterlin Marsh: a protected natural area
Classified by the Conservatoire du Littoral, the Mousterlin marsh is a major ecological heritage site in South Finistère. People come here for the special atmosphere that reigns between these stretches of fresh water, reedbeds and wet meadows.
Practical tips for your visit:
- Stay on marked trails to preserve fragile vegetation
- Choose the early hours (7am-9am) to observe the wildlife
- Bring binoculars: grey herons, egrets and wild ducks are regular visitors.
- Keep quiet to avoid disturbing nesting species
The Fouesnant Tourist Office regularly reminds us of the importance of these good practices, which help maintain the fragile balance of this ecosystem.
The great beaches: swimming and relaxation
Mousterlin is renowned for its long, ocean beaches, ideal for combining walking and swimming. The fine sand stretches for several hundred meters, offering plenty of space even in summer.
Points to watch:
- Watch out for swimming flags and respect authorized areas
- Beware of currents during high tides
- Don’t trample the dunes: dune vegetation retains the sand and protects the coastline.

Nature activities: how to enjoy the site
The GR34 Douaniers trail: the flagship itinerary
Mousterlin lies on one of the most beautiful stretches of the GR34 in Southern Brittany. The coastal path, also known as the sentier des Douaniers, crosses a variety of landscapes between Beg-Meil and the pointe de Mousterlin.
Our suggested route (easy to medium level) :
- Start : Cale de Mousterlin
- Direction: Beg-Meil via the marsh (8 km one way)
- Duration: 2h30 to 3h depending on your pace

A YouTube video documents the ambience of this stretch of the GR34 between Bénodet, the Mousterlin marshes and Beg-Meil, giving you a good idea before you head out.
Alternative for a shorter circuit: Boucle pointe + marais (4-5 km, approx. 1h30). Ideal for a family outing.
Kayak and stand-up paddle: explore differently
Local service providers offer supervised kayak and SUP outings in the Fouesnant-Beg-Meil-Mousterlin area. These activities enable you to discover inaccessible coves on foot and observe the coastline from the sea.
The Fouesnant-based “Get Up Stand Up” school organizes itinerant rides for beginners and advanced riders alike. Wingfoil is also on the rise for those looking for a more sporty thrill.
Birdwatching: a paradise for enthusiasts
The Mousterlin marsh is a prime site for birdwatching in Southern Brittany. The diverse ecosystem attracts a wide variety of species all year round.
Species regularly observed:
- Grey herons and little egrets
- Mallards, teal and shelducks
- Migrating waders (avocets, redshanks)
- Cormorants and gulls in the maritime area
