The Moulin de l’Éclis, nestled along the Atlantic coast in the commune of Assérac, Loire-Atlantique, perfectly embodies the subtle blend of historical heritage, unspoiled nature, and seaside relaxation.

Located just a stone’s throw from the famous Guérande Peninsula, at the gateway to the Brière Regional Nature Park, the Moulin de l’Éclis site stretches between the ocean, salt marshes, and vast wooded areas. Its name comes from an old tidal mill that once used the power of water retained by a sluice gate (“éclis” being an old form of the word “écluse”) to grind grain—an echo of a rural lifestyle deeply rooted in the maritime environment. Although the original mill is no longer active, its name lives on as a tribute to this agricultural and seafaring past.

Today, the Moulin de l’Éclis is above all a popular tourist destination, notably thanks to its namesake 4-star campground. This large, wooded estate opens directly onto one of Assérac’s most beautiful beaches—a vast expanse of fine sand kissed by the tides of southern Brittany.

The beach at Moulin de l’Éclis is both family-friendly and peaceful, ideal for swimming, beach games, or simply relaxing by the ocean. Lined with gentle dunes and sheltered from urban bustle, it offers a natural setting of great serenity. At low tide, beachcombers joyfully scour the sandbanks in search of clams and cockles.

The campground itself stands out for its spacious accommodations and modern amenities: a heated aquatic area with slides, a spa, playgrounds, sports courts, summer entertainment, a restaurant, and an on-site mini-market. It welcomes families, couples, and groups of friends seeking nature, comfort, and the seaside.

In the background, the Mès salt marshes—an extension of the Guérande marshes—unfold their glittering grid between land and sea. These are cultivated by salt workers who perpetuate centuries-old techniques, offering visitors a poetic display through the seasons and a chance to discover a unique artisanal and ecological heritage.

Nearby, several hiking trails allow for the exploration of this lesser-known yet stunning stretch of the Atlantic coast. The GR34, the iconic coastal path, runs nearby and connects wild beaches to charming villages such as Pénestin or Mesquer, following hidden cliffs and picturesque coves along the way.

The Moulin de l’Éclis thus represents an ideal destination for sustainable tourism, in harmony with the sea, the forest, and local traditions. Whether it’s lounging on the sand, cycling or hiking, exploring the salt marshes, or sampling local products, visitors enjoy a full immersion in the gentle way of life found on the Breton Atlantic coast.

In every season, the site enchants with its soothing atmosphere, the variety of its landscapes, and the richness of its heritage. A small corner of paradise where one can breathe in the salty sea air, the scent of maritime pines, and the discreet charm of an authentic shoreline.
