A very beautiful city, both for its iconic port at the foot of the rocks and for the old town and its charming alleys.

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.

It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.
