The source of the Doubs River is a powerful karst spring in a heavily karstified area of the Jura Mountains. It lies at an altitude of 937 meters at the foot of the forested, up to 1,419-meter-high Mont Risoux mountain range, which straddles the border between France and Switzerland. The Doubs River rises from a small, approximately five-meter-deep spring basin in a cave in the rock.

A former, unlit railway tunnel with a length of 180 meters. A flashlight is extremely helpful here, as there are quite large stones in some places that are invisible in the dark.

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.
