A particularly pleasant walk from the campsite along a section of the lake. There are a few challenging climbs, so good footwear and drinks are recommended. There's a restaurant along the way, with limited opening hours. Can be slippery in wet weather.

A natural setting of great beauty, but which has been created by man. This place of calm and relaxation is very popular for this reason. When the reservoir was created in 1978, a village was submerged under water and the Grange de la Baudrière, located nearby, is the only survivor.
