Please note, this hike was done in May 2025, and the very last section was inaccessible. We were unable to reach the source of the Cusancin River; fallen trees and overgrown vegetation made the path impossible to find. We had to turn around and return to the starting point by road (barely a hundred meters of asphalt).

Built on the foundations of a 12th century feudal castle, the chapel dominates the hamlet of Val-de-Cusance. It was built in 1880 and bears the name of Saint-Ermenfroi, who had built an abbey intended to accommodate the sick and foreigners in the 7th century. The chapel is the ideal place to enjoy a beautiful panorama of the valley, with greenery as far as the eye can see.

The green spring or the Cuse is located on the left side of the river at approximately the same height as the blue spring. This is the true source of Cusancin. The upper gallery of the cave was walled with dry stones.

The blue spring is a Vauclusian spring which emerges in an oval basin. Its depth is nine meters. Divers explored the submerged gallery over a length of 220 meters before stumbling upon a narrowing which was not crossed. The gallery is made up of two siphons. The turquoise blue waters give it its name.

It is one of the two sources that feed the Cusancin, a river also known as “the Cuse”. It is greener than the blue of the Cove which is called the Blue Source. This is on the other side of the road. The Cuse and the Anse join and lend their name to the neighboring village: Cusance.

As the name suggests, this water is crystal clear sea blue. Is it worth visiting and maybe taking a dip?
