The salt marshes give Batz-Sur-Mer a distinctive character: they cover 459 hectares and are also private working and production areas. Visitors may not enter without an invitation. Those interested in the salt landscape can explore the subject in different ways. The Musée des Marais Salants is housed in former salt warehouses; its tour explores the heritage and area of the salt marshes on the Guérande peninsula. There is an educational trail at the Dune de la Falaise; the dune is home to many protected plant and animal species.
Salt Country, a Mill and the History of the Fortifications
The Musée du Grand Blockhaus offers a different historical perspective: it is a five-storey combat command post from the Second World War’s Atlantic Wall and presents the history of the Saint-Nazaire fortress. The Moulin de la Falaise combines architectural history with milling technology that is still in use today. The mill dates from the 16th century and was rebuilt exactly as it was in 1925 at its current site on the dune. Its traditional mechanism is still used by a miller to process organic buckwheat grains into organic buckwheat flour.
Churches, Chapels and Lanes in the Town Centre
The 1.3-kilometre Cœur Historique circular route takes visitors on a walk through the town centre, including to the Église Saint-Guénolé, the Chapelle du Mûrier and the Musée des Marais Salants. The Chapelle du Mûrier is a Flamboyant Gothic chapel dating from the 15th century and is now a ruin. Several works by Jean Fréour can be seen in the Église Saint-Guénolé, including Notre-Dame du Précieux Sang, Christ en croix and La Sainte Famille. The church tower was built in the 17th century. The 70-metre-high Tour Saint-Guénolé offers views of the ocean and salt marshes; visibility depends on the weather. The terrace is accessible via an interior spiral staircase with 184 steps.
The protected lanes in the town centre, known as venelles, are also part of the town’s architectural character. For a walk, you can compare the 1.3-kilometre Cœur Historique with the 5.5-kilometre Sentier des Douaniers: the first passes through the town centre to named cultural sites, while the second is a coastal circular route.
Paludier Villages and Their Details
Kervalet is one of the traditional paludier villages of Batz-sur-Mer. Trégaté is perched on a rock; its features include narrow lanes, stone houses, a communal bread oven, a well, a granite calvary and 18th-century dormer windows. In Kermoisan, a mural on the water tower depicts the work of the paludiers. In Roffiat, there is a wooden cross decorated with thirteen hearts and a statue of Notre-Dame du Bonheur.
La Croix de Trégaté also has a story of its own: the granite cross replaced a cross several centuries old in 1937, after it was knocked over and broken by a truck. Together with the chapel, the church tower and the villages, these varied structures offer concrete points of interest for getting to know Batz-sur-Mer through its local history.
Coastal Trails and Activities on the Water
The Sentier des Douaniers is a 5.5-kilometre coastal circular route. The Vélocéan cycle route passes through Batz-sur-Mer and offers views of the region’s natural landscapes and cultural heritage. The two routes have different focuses: a circular walk along the coast and a cycle route with views of nature and culture.
Water sports add to the range of activities along these routes. The École de Voile Valentin offers seasonal windsurfing, introductory dinghy and catamaran sessions, sailing trips and coastal cruises. Surfing, bodyboarding and stand-up paddleboarding are available at Plage de la Govelle; water conditions and activity availability vary by season. At low tide, visitors can find shellfish and crustaceans while shore gathering. During spring tides, the tourist office offers introductions to this activity; local rules apply. Conditions therefore differ when planning: water sports depend on the season and water conditions, while shore gathering depends on low tide and local rules.
