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.

Langouette waterfalls and gorges

Highlight • Gorge

In Les Planches-en-Montagne, hide the little-known Langouette gorges.

The Saine river passes through a rocky defile, 40 meters deep. The watercourse will alternately take on the appearance of whirlpools, waterfalls and basins. All in a setting of mosses, ferns and trees.

It is a remarkable natural site.

It is a natural lake of glacial origin with a wild appearance. This lake will surprise you with its turquoise shores on a clear day and its cliffs in the background. It is otherwise known as Lake Ilay. With an area of 72 hectares and an average depth of ten meters, it is fed mainly by Lake Grand Maclu, to which it is connected by a small natural canal approximately 200 meters long. Possible activities: Hiking (tour of the three lakes/four lakes) and mountain biking (tour of the five lakes), horse riding, holiday activities and entertainment... Swimming is tolerated, under your own responsibility.
