クランの天然記念物・トップ15

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.

Lac d'Ilay, also called Lac de la Motte, is a lake in the Jura department of France, about 14 km south of Champagnole in Franche-Comté. It lies at an altitude of 774 m in the municipalities of Le Frasnois and La Chaux-du-Dombief and covers an area of approximately 0.7 km². The lake is 1.9 km long, has a maximum width of 400 m, and has a small island (Île de la Motte). Its greatest depth is 32 m.

Lacs de Maclu are two adjacent lakes in the western part of the French Jura, in the Jura department of Franche-Comté. They are located at an elevation of 779 m in a depression in the High Jura, in the region of the Five Lakes near Le Frasnois, about 12 km south of Champagnole. The Petit Maclu, located to the northeast, has an area of 5 hectares, a length of about 500 m, and a maximum width of about 120 m. Its greatest depth is 11 m. It lies entirely within the municipal territory of Le Frasnois.

waterfalls don't always flow

Easy, shaded path, perfect for cooling off in hot weather.

Very nice walk but a lot of tarmac

The tour of the lakes is not of much interest, mainly being wide paths, without much relief, and with no view worthy of the name, including on the lakes (which we see very little, except on the eastern part, which is a shame). The western part is even difficult (we follow the road for 2km...). In short, a walk to forget, except perhaps for a running outing, or a detour via the Eagle peak.
