The Gorges de la Langouette are impressive for their vastness and the uniqueness of their wild environment. With the many light effects illuminating the mosses and ferns growing beneath the wooded canopy, they exude a gentle and tranquil atmosphere, particularly conducive to relaxation. This unspoiled spot offers a privileged view of the water's work, carving the canyon with its capricious meanders. The Petit Saine River, roaring and unpredictable, overcomes all obstacles to continue its course before converging with the Ain a few kilometers further on.
