Pic de l'Aigle

Highlight • Summit

At the summit of the Pic d'Aigle at an altitude of 993 meters, which is often also called Bec de l'Aigle, the whole of the Jura rises up at your feet. You can see the Ilay gorges which cross the heights of La Chaux-du-Dombief. On the left, you can see the Jura mountains behind which rises the summit of Mont Blanc in good weather. The plateaus above the Saône plain are also visible on the right.

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.

Bief de la Ruine Waterfalls

Highlight • Waterfall

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.

Tunnel de 180 m de long sur la Tramjurasienne editorial name for French users

Highlight (Segment) • Other

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.

September 17, 2025,Belvedere des 4 Lacs mit Geistertunnel 👻🇨🇵

The conditions were much better for biking today, but still very wet.

The terrain changed constantly, which continued throughout the entire tour.

The highlight was definitely the four lakes with their beautiful colors 🤗 and the section along the old railway line with the 180-meter-long (short) tunnel 👻👍 be sure to bring a lamp 🔦
We actually wanted to have …
