The Grouin du Sud is a natural headland offering impressive views of the bay and the famous Klosterberg. Depending on the tide, the landscape alternates between vast mudflats and ocean views, making the place particularly charming.

Beautiful place. Because of the perfect view of Mont St Michel. You can see the rock beautifully in the middle of the water.

First tourist site in France outside the Paris region, Mont-Saint-Michel is famous for the rocky islet on which its abbey was built. The bay in which it sits is known for its tides, which are said to move as fast as a galloping horse. The setting offered by the site is simply magical. A place of pilgrimage since the 9th century and a stopover on the Santiago de Compostela route, the abbey is also a major religious place. In addition to the abbey church, the medieval town is also an architectural gem, with its courtyards, walkway and châtelet.

The Château d'Avranches was built around 950 by Onfroi Le Dane, on the remains of the old Roman walls. Located on a rock, the fortress could monitor the bay of Mont-Saint-Michel and the various invaders made no mistake and occupied it; Celts with the Abrincates, Romans, Saxons, then Franks. A succession of enclosures and ditches were added to it. The Roman keep unfortunately disappeared in the last century. The top of the curtain forms a platform at the same level as the terrace. A diagram, made by Canon Pigeon, shows how keep and curtain wall were connected. This is also verifiable in a document kept in the Calvados Archives. Another detail should be noted, it is impossible to access the terrace from inside the building. Passages were obstructed after a collapse of the upper level of the building, at an undetermined time. Today, at the top of a crenellated curtain wall, one discovers a panorama over the bay and the valley of the Sée, in the heart of the various Avranchinese districts.
