Lake of Castillon

Housed in the heart of the Verdon Natural Regional Park, the Lake of Castillon is a real invitation to swim and relax. It is the second largest lake in the region after the lake of Sainte Croix (500 ha) and is located north of Castellane in the Alpes-de-Haute-Provence department. It results from the construction of a dam in a natural narrowing of the Cheiron hill. It took 20 years to build it in order to create this retention basin which engulfed the village of Castillon and the bridge of Saint-Julien when it was put into water. The road that passes over the dam offers a breathtaking view of the Verdon River flowing downstream. The largest sundial has been installed on the curved wall of this impressive construction, which is 200 meters wide and 95 meters long.

The lake of Castillon offers landscapes that stand out from those of Sainte-Croix, which are more frequented. The fauna and flora that have developed there are reminiscent of the alpine environment. Yachtsmen can breathe at full lungs, as they benefit from the pure air coming straight from the Alps.
