The Couesnon at Beauvoir

Highlight • River

The Couesnon is a small river which flows into the ocean at the level of Mont-Saint Michel. The Véloscénie runs along this river for a few kilometers before reaching the famous islet. This last stage of the cycle route offers magnificent views of the Mont-Saint-Michel abbey.

Couesnon dike

Highlight (Segment) • Cycleway

The Couesnon dike connects the mainland to Mont-Saint-Michel by crossing the polders. By bike, it offers a unique perspective of the bay and its expanses. This rolling, windy section gives the approach to the Mont its character.

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.
