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.

At 3 km long, this is the largest sandy beach in Saint-Malo. Walking along this beach, you can reach Intra-Muros in Paramé. Sillon Beach includes Grande Plage, Hoguette Beach, and Rochebonne Beach. La Digue was built from 1883 to 1913 on an old sandbar (the Sillon) that once connected Paramé to the walled city and provided the only dry-land access at low tide. Originally, a strip of sand was covered with dunes that grew higher and higher as one moved toward Rochebonne, with only a succession of windmills remaining. The first causeway was built in 1509, rebuilt and widened several times... Le Digue, 1,671 meters long, runs along Grande Plage and offers a pleasant stroll, lined with numerous villas built towards the end of the 19th century. Along the Sillon, a line of breakwaters protects the seawall from the force of the waves. Built in the early 19th century based on an idea by the civil engineer Robinault de St-Servan, the oak breakwaters have a depth at least equal to, or even greater than, their visible height.
