La Roche Torin is a prominent vantage point in the Bay of Mont Saint-Michel. This spot offers a unique view of the bay and is a popular destination for hikers and photographers, especially during strong tides (coefficient over 100). The tidal coefficient is the most important indicator for assessing the dynamics of the bay. A coefficient over 100 indicates spectacular tide conditions and a natural spectacle. Here in the Bay of Mont Saint-Michel, the highest tides in Europe occur, with a tidal range of up to 15 meters between high and low tide.

A bridge with a long history! Even the Romans passed along here! And at the end of World War II, American troops passed through here to liberate France. Today, people make pilgrimages past the bridge on their way to Mont St. Michel.

The “Pont de Pontaubault” is a beautiful work of art, the construction of which dates back to the 15th century. It is the first bridge to cross the Sélune, between Saint-Quentin-sur-le-Homme (right bank) and Pontaubault (left bank). It is located on the old road from Avranches to Rennes, via Saint-James. Since the arrival of the A84 motorway it has mainly been used locally. The bridge has eleven arches and is built with stone masonry. There is a picnic area at the bridge, near the railway viaduct of the Caen-Rennes line, not far from the salt meadows where sheep graze. During big tides many spectators and kayakers come to enjoy the spectacle provided by the tide. The bridge has a rich history. It was bombed several times during World War II but withstood these attacks, allowing 100,000 men and 1,500 vehicles to cross. A memorial plaque recalls that "the fate of the war lay on this bridge".
