Nothing's better than unwinding by the water while you're on vacation. Take a picnic to Lac de Castillon and then hang around for a peaceful sunset.
To visit this body of water, make your way to Alpes-de-Haute-Provence. There are lots of other things to see and do in the area, such as Base Sport Nature, Musée Sirènes et Fossiles, and Planete Riviere.
