South of the Mouthe valley, a succession of forests and pastures, punctuated by two belvederes: a recent one at the Côte Feuillée to learn about ski jumping and its history, and the Roche Blanche in Chatelblanc.
This circuit starts out strong. From the Côte Feuillée belvedere and its breath-taking view onto the ski jump stadium, take a moment to imagine yourself flying through the air and to feel the adrenaline provided by this spectacular discipline in which athletes slide down the ramp at speeds approaching 100 km/h before taking flight. This place will give you wings…

  • History & Heritage

    The old cheese dairy of Chaux-Neuve

    The architectural shape of cheese dairies is often very different to that of houses. The location of the cheese dairy in Chaux-Neuve, in the centre of the village, tells us that it was considered a public building almost as important as the church, the town hall or the school.

  • Viewpoint

    Travel to the world of ski jumping from the belvedere of the Côté Feuillée

    Three ski jumps, resembling the edges of knives, attack a rocky hillside; the Côte Feuillée is a natural site favourable to ski jumping. In the Chaux-Neuve stadium, an interpretive circuit allows visitors to appreciate this sporting landscape, with its summit offering a unique sense of a ski jumper’s feelings. An exhibition and a film presenting the Nordic combined, a sporting skill, and a true local way of life. Every year, “chauniers” (inhabitants of Chaux Neuve) welcome thousands of spectators during international ski jumping and Nordic combined competitions organised on this site.

  • Flora

    Fir tree or spruce?

    The High-Jura is well-known for its softwood forests, comprised of fir trees and spruces, two species with shared characteristics (conical shape; and with persistent needles). How to differentiate between them?

    On the fir tree, cones are directed upwards, its flat needles have two white lines on the underneath and their position on either side of the sprig is reminiscent of a comb; whilst on the spruce, cones fall downwards, the needles are sharp and positioned like a brush, all around the sprig.
  • Viewpoint

    Belvedere of the Roche Blanche

    Looking over the village of Châtelblanc at an altitude of 1,013 m, the belvedere of the Roche Blanche offers an in-depth view over the Val de Mouthe to the north, and over the high valley of the Saine and the isolated farms lining the forest of the High-Joux to the south.


Starting at Cébriot (stream) facing the town hall, the trail heads up the village (white and red waymarking) to LERNIER, before (yellow and blue waymarking) following the D 46 and reaching l’Estanguillon.

The path heads up to the right through a valley with a small stream before exiting onto Sur la Chenoz where the first house's dam is proof of the existence of a former mill. The path then turns abruptly to the right, to access the COTE FEUILLEE.

The trail continues on a path that descends into a forest to the left (pay attention to the waymarking) until it reaches the Place à bois des Serments.

The path to the right, which is suitable for vehicles (white and red waymarking) passes through a combe to les Serments, and then (yellow and blue waymarking) comes to Bois des Ravières.

The Bridaux forebay waterfall and the vestiges of its mill can be accessed within 5 mins via LA SCIE. Be careful!

The route heads upwards towards Chatelblanc and quickly reaches (100 m) La Combette de la Roche. A grassy trail crosses through a pasture (MTB path) before exiting onto the Grand Réservoir.

The panoramic view from Roche Blanche is then accessible within 5 mins (there and back). Be careful!

When you have returned from the viewpoint, the good farm road that pleasantly overlooks the combe to the east joins up with "Chemin de la Roche" after a sharp bend to the left.

A barely-signposted trail to the right in the combe (MTB path) cuts through the meadows, joins up with a path and opens out into the heart of Chaux-Neuve, behind the old cheese dairy.

Altimetric profile


Be careful alongside the départementale road between Le Lernier and l’Estanguillon, around the Roche Bloche viewpoint and near the Bridaux forebay waterfall.

This trail passes through private property pastures with livestock and forest paths. To respect the owners and farmers granting you passage, and for the security of livestock and wild fauna, we ask that you remain on the waymarked paths. Use the adapted passageways to get across fencing and be sure to close gateways behind you. Lastly, please keep your dog on a lead if you have one.

Wild flowers are beautiful, they may be rare and protected and often wilt quickly. Do not pick them! They will delight the next hikers.

In case of forest works (felling, skidding, etc.), for your safety, know when to stop and turn around.
