Probably the most ethical lock in the area. Everything is local, and the welcome is warm.

Nicknamed the «pearl of the Erdre», the port of Sucé-sur-Erdre is an unmissable charming stopover where lively terraces and pleasure boats coexist in a green and peaceful setting. It is the ideal starting point for strolling along the quays or taking a trip on the water, to discover one of the most beautiful rivers in France.
