The peninsula of Saint-Suliac is located on the river Rance. At low tide, the beautiful mud flats and salt marshes appear. The route largely follows the path along the river with beautiful views along the way.

This walk goes from Ans du Verger over the Sentier des douaniers (GR34) to the Pointe du Grouin. Here you have one of the most beautiful views of the bay of Mont Saint-Michel, the emerald coast and the islands of Chausey. From the viewpoint you continue along the coastal path in the bay to return via the interior to the nature reserve Le Verger.
