Unfortunately, the chapel was closed, a look through a recess in the door. And again and again the view of Mont-Saint-Michel

Mont-Saint-Michel is a world-famous rocky island and commune on the border between Normandy and Brittany in France. Crowned by a monumental, medieval Benedictine abbey, this architectural marvel has been a UNESCO World Heritage site since 1979. The bay of the mount is also known for Europe's strongest tides, with a tidal range of up to 14 meters.

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.

The Couesnon dam (Barrage du Couesnon) was completed in 2009 and is part of the measures to preserve the bay of Mont-Saint-Michel. The facility regulates the water flow of the Couesnon and supports the natural removal of sediments by the tides. This is intended to counteract the increasing silting up of the bay and preserve the special character of Mont-Saint-Michel as a tidal island. The dam also offers a popular viewpoint with a view of Mont-Saint-Michel and the surrounding salt marshes.

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.
