The three rivers of the Bay of Mont.
Departing from the Couesnon, we'll follow the dyke or the grasslands to the Sélune and round its mouth. We then head up the Sée as far as Avranches. During high tides, tidal bores travel up these two rivers.

    German Ossuary of the Mont d'Huisne

    Located opposite Mont St Michel, near Avranches, where, on 30 June 1944, the Allies made a decisive breakthrough in the German defence following the Normandy landings, this mausoleum was built between 1961 and 1963 on a hill some thirty metres high. It contains the bodies of 1,956 German soldiers from the Grand Ouest and the Channel Islands. It is a ring-shaped, buried building with an internal diameter of 47 metres. It has 68 crypts on two levels, each containing 180 bodies. A large cross stands at its centre.
  • Historical

    The Roche Torin dam

    In 1857, plans were made to build a dike from the Pointe de la Roche Torin to the Mont St Michel in order to create new polders. It was never completed. 
    Blocking the sediments, the part that had been built led to the extension of the grasslands. Several studies have shown the disastrous consequences for the maritime character of the Mont.
    Its destruction began in 1983, marking the start of work on the bay.
  • Historical


    Before arriving in Pontaubault, you can see a small oratory in the cliff.
    Pontaubault is located at the mouth of the Sélune and was one of the first crossing points between Normandy and Brittany.
    The various metal bridges were used for railway lines, one of which is now abandoned and converted into a greenway.
    The first stone bridge was built in the 15th century, close to a Roman road. In 1793, it saw fighting between Chouans and Bleus. On 1 and 2 August 1944, it saw the passage of Patton's army.


Leaving the Mont, cross the access bridge again and, at its end, turn left onto the red/white signposted path that follows the dyke at the top of the grassland. Follow the dyke as far as "Le Rivage" where it meets the D275:
  1. Follow the road to the left and, after the car park, take the left-hand fork in the signposted path along the dyke. Continue as far as the pointe de la Roche Torin.
  2. Go around the point and follow the D313e. Continue as far as the crossroads with the D113. Turn left and follow the upper part of the grassland as far as Pontaubault. Pass under the metal bridge and cross the Sélune by the stone bridge.
  3. When you come out of the bridge, turn left onto the signposted path that follows the upper part of the grassland. Continue as far as the Avranches water treatment plant.
  4. Continue along Rue des Grèves until you reach Rue du Pont Gilbert. Turn right onto this street, cross the railway tracks and follow the station to the right.
  5. Once past the station, follow the signs for the pedestrianised town centre. Cross the footbridge over the Autoroute des Estuaires and walk up the Chemin du Tertre de la Gare. At the roundabout with the D7, go straight ahead and then turn left onto the Promenade Pierre Aguiton. Walk past the Town Hall and turn left into rue d'Islande and place d'Estouteville, as far as the Scriptorial museum.
