Old mill dating from the 16th century. Located on private property, but relatively visible from the road. Whether you climb up from Angellerais by road or via the GR3 trail, it will require a good effort.

A pleasant little detour on the road to Pontchâteau. The Moulin de la Lande is a lovely place to stop and relax—a peaceful spot with an open view and an authentic atmosphere. Formerly a windmill belonging to the commune of Pontchâteau, the Moulin de la Lande bears witness to the region's milling past. Today, it stands in ruins.

As its name suggests, this is the largest beach in Préfailles. Lively and supervised in the summer.

Sainte-Marguerite Beach is the smallest of Pornichet's three beaches. For a complete immersion in the Pornichet of yesteryear, this is the perfect place. Lined with old-world villas and surrounded by wooded surroundings, it's a favorite with lovers from near and far, as well as locals who appreciate its discreet atmosphere. People love swimming here in the summer and strolling there in the fall, in a gentle and romantic atmosphere. On site: snack bar, restaurant, sailing school, beach club, lifeguard station, and restrooms. Swimming is supervised in July and August.
