Numerous inlets criss-cross the meadows and channel seawater through the vast terrain at low and high tide. These small watercourses with their reflections and the wide grassy areas also form a popular photo spot and offer impressive motifs, especially with Mont-Saint-Michel in the background.

The salt marshes of the Bay of Mont-Saint-Michel shape the unique landscape of Normandy. Regular flooding with seawater creates a special vegetation that is perfectly adapted to the saline conditions. The famous salt marsh sheep (*Prés-salés*), whose meat acquires a special flavor due to their special diet, graze in these meadows. The vast areas are also a valuable habitat for numerous animal and plant species and offer an impressive view of Mont-Saint-Michel at low tide.

Narrow tidal channels crisscross the salt marshes around Mont-Saint-Michel like fine veins. At high tide, they fill with seawater, and at low tide, they channel the water back to the open mudflats. This constantly changing network of channels shapes the unique landscape of the bay and, from a bird's-eye view, resembles a branching river system.

Lovely route, first along the coast on good cycle paths, then after the large car park via all sorts of narrow roads and villages back to the campsite in Ceaux.

Perched high above the coast of Saint-Jean-le-Thomas, with breathtaking views of the Bay of Mont Saint-Michel, stands the Cabane Vauban – a silent witness to a bygone era. This small stone hut dates back to the 17th century and was built during the reign of the great fortress builder Vauban. It once served as a watchtower, monitoring the coast and controlling smuggling.
