The dam on the Couesnon

Highlight • Other

The footpath along the Couesnon to the dam already offers an impressive view of Mont-Saint-Michel. From here, the path with an unobstructed view leads across the salt marshes and the bay, with the landmark of Normandy impressively rising against the wide landscape. Especially in calm weather and with changing light, atmospheric views emerge of Mont-Saint-Michel, the course of the Couesnon river, and the tide-shaped surroundings.

Mont Saint-Michel Causeway and Dam

Highlight • Bridge

The tidal dam over the Couesnon not only offers an interesting technical aspect, but also a wonderful setting for hiking and cycling in the region around Mont Saint-Michel. The dam controls the inflow of sea water and thus creates a unique landscape that changes between the tides. The comfortable bridge takes you to the vast polder areas, where nature shows its gentle and calm side. The path along the river leads directly to the impressive Mont Saint-Michel, always with a view of the historical landmark.

From the Couesnon dam bridge, you have a wide-angle view of Mont-Saint-Michel and its bay. Make a short stop before setting off on the long road to Rennes.

@ Les Guilvinistes: this tip is wrong. Both bridges are in Pontorson, including the pedestrian bridge.

Cycle path along the Couesnon River

The Couesnon is a small coastal river that flows into the bay of Mont-Saint-Michel. As you walk along its banks, approaching the coast, views of the incredible monument unfold one after another.
