Entre lac et rivière - 12 km

This circuit starting from Sainte-Marie-du-Lac-Nuisement will take you towards the Blaise Valley and Arrigny and then bring you back to the north shore of Lac du Der where you can choose to follow the dike of the basin returning to the port of Nuisement or continue along the dike towards the west and return by the small dike separating the lake and the northern basin. Don't miss the visit to the emblematic Village Musée du Der to learn more about the history of Lac du Der and its heritage. Please note that this walk is not accessible from the end of May to the end of July. You can then opt for the 9km variant.
