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.

The most touristic of the eight islands that make up the commune of Saint-Joachim, notably for its famous thatched cottages typical of Brière and its Michelin-starred restaurant, La Mare aux Oiseaux.

17th century chapel built on the site where St Friard and St Secondel lived. A little further along the path you will find an oratory built above the fountain where the saints collected their water.
