The Bief de la Ruine waterfall is located in the spectacular Malvaux Gorge. One of the most astonishing features of this waterfall is the fact that it only comes alive after heavy rainfall or during snowmelt. When it dries, it gives way to the spectacle of the carved stone, revealing the "Creux des Joyaux," a natural cave where the water swirls with varying degrees of vigor, polishing a multitude of limestone pebbles thanks to the force of its current.

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.

Very easy to access following the Jura Z between Foncine le Bas and Planches en Montagne, along the SAINE gorges: The color of the water has nothing to envy of that of the lagoons of the islands ;-)
