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.

Small, rocky stretch of beach that you can climb down to, as well as good views of Lac Le Grand Maclu.

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.
