Charmes-sur-l'Herbasse Castle

Highlight • Other

On the heights of Charmes-sur-l'Herbasse, this castle is also nice to visit. It gives a beautiful view of Lake Champos and the surrounding hills. Also accessible on foot or by car via a small winding road.

Col de la Madeleine (Chambarans)

Highlight • Mountain Pass

Not to be confused with the other Col de la Madeleine in Savoie. This is a much smaller and gentler climb. The views at the top are nice nonetheless.
