A short, shaded and pleasant family trail, allowing you to discover the Lac des Rouges Truites bog and its fragile and unique ecosystem, which is a delight for nature lovers: rare plant species and animal species, some of which are endangered, live happily here.

The Malvaux and Langouette Gorges offer cool respite on hot summer days as well as magnificent scenery. This hiking route is suitable for families, with a shorter alternative (9.5 km) that does not go around Lac à la Dame. Part of the route follows the old tramway, so a head torch or torch is required to cross the 180 m tunnel.

The village of Les Planches-en-Montagne has a picturesque gem at its heart: gorges carved into the limestone and well hidden under the trees. The Saine rushes through them with gusto. Force, turmoil and noise coexist here with calm, serenity and gentleness.

The landscape and soul of Grandvaux are revealed throughout this iconic route: forest valleys, meadows and pastures, and the church by the lake.

A journey to the heart of water... nourishing for people and their animals in the countryside, driving force for industry in the city. Explore the typical landscapes of the Haut-Jura: forests, valleys, pastures, gorges, lakes, peat bogs and rivers.

This route is designed for electric hybrid bikes; you will not find any signposts along the way.Your route will take you along tarmac roads, carriageways, footpaths, forest tracks, etc. Given that you will be passing through a relatively long old railway tunnel and considering the length of the route, be sure to bring a torch or other lighting and a spare battery.

Twelfth stage of the Échappée Jurassienne. For this stage,prepare to be amazed by the wild and authentic beauty of the Jura as you let yourself be carried away by the water for a peaceful break, out of time. Follow the tumultuous course of the Saine River through theLangouette Gorges, then discover the village of Les Planches-en-Montagne and the spectacular Malvaux Gorges, where the Saine has formed the Cascade du Bief de la Ruine, the largest waterfall in the department with a drop of 110 metres. The river then winds its way under the viaduct of the old tramway towards Foncine-le-Bas, offering breathtaking natural landscapes. Finally, cross the Mont Bayard at an altitude of over 1,000 metres for a remarkable view of the surrounding mid-mountain landscape. End your day with a descent to the village of Foncine-le-Haut, ideal for a restful and rejuvenating night.

A hike to do preferentially during fall to admire the beautiful colors of the Indian summer reflecting off the lakes.

Very nice and easy walk above the lakes of the Jura, Maclu and Illay. Important note regarding parking: this site is particularly busy and has three car parks numbered P1, P2 and P3. We strongly recommend parking in car park P1, which can be accessed via this link.

From the rocky ridge that marks the transition from the lake region to the Grandvaux plateau, the Pic de l'Aigle and the Belvédère des Quatre Lacs emerge during a wooded and lakeside walk.

Thirteenth stage of the Échappée Jurassienne: discover the Jura Mountains on this stage between Haut-Jura and Haut-Doubs. Explore the cross-country ski trails of the Mont Noir massif, which are transformed into superb hiking trails in summer. Immerse yourself in a peaceful, unspoilt environment, where alpine flowers bloom alongside the woody scents of fir and spruce trees. Between the woods, valleys and ridges, enjoy the fresh air while admiring the picturesque landscapes. This stage will also take you along the Bellefontaine and Mortes lakes, known for their peat bogs, which are home to remarkable flora and fauna.

This magnificent route, ideal for families, overlooks Lake Ilay with a panoramic view of the entire Jura mountain range and the Alps in the background. Marked with cairns, the route offers a fun walk full of discoveries.

The Pic de l'Aigle dominates the valley of the 4 lakes, offering magnificent views of the entire Jura plateau, the Vallée du Hérisson, Grandvaux and even Mont Blanc on a clear day. Starting from Lac d'Ilay, you will climb up to this splendid line of ledges and its viewpoints over these turquoise lakes.

This magnificent hike will take you along the Cascades du Hérisson waterfalls and around Lac de Bonlieu. Don't forget your camera, as there are some magnificent views. Please note that from the point (4), the trail is temporarily closed due to a landslide.

The walk descends the Hérisson ('hedgehog') River with its series of rapids and waterfalls, then returns via Bonlieu, passing through the Dame Blanche viewpoint, with a panoramic view over lakes Val and Chambly and the Herisson valley.

An iconic site in the Jura: the Hérisson waterfalls. This route allows you to discover all of the Hérisson waterfalls, starting from the top of the falls. Allow 3 hours for the round trip along the 7 Hérisson waterfalls. If you prefer to admire the two largest waterfalls, "L'Éventail" and "Le Grand Saut", without hiking for three hours, we suggest parking at the Maison des Cascades in Ménétrux-en-Joux, from where you can quickly and easily reach the foot of L'Éventail. The Hérisson waterfalls can be very busy in summer, so spring and autumn are better times to visit.

A beautiful hike around the famous Cascade de la Billaude waterfall, which you can admire on the way there or back. The route runs alongside the bucolic Étang des Pêchettes lake and leads you to a surprising and fairly challenging passage, the Grande Cheminée. It also passes by several viewpoints, including those at Prés Grillets and Taiclet. Those who wish can climb up to the drystone shelter at the Ours (cave) and enjoy a clearing in the vegetation to see Champagnole and its surroundings. You will enjoy the coolness of the banks of the Saine and, at the confluence with the Lemme, you will climb up to the waterfall.

From the car park in the hamlet of La Fromagerie, which also provides access to the Cascades du Hérisson from above, cross Le Frasnois and follow the banks of Lac de Narlay before climbing up to discover several magnificent viewpoints overlooking the emerald-coloured lakes (Ilay, Narlay, Grand and Petit Maclu), some of which are unnamed and wild, and those of the Quatre Lacs, Trois Lacs and Pic de l'Aigle, then return to the starting point along the Lac d'Ilay.

A trail starting out from Foncine le Haut that will take you to the source of the Saine and various viewpoints. A themed trail and a botanical trail...

The Saine river has its source in the shelter of this limestone amphitheatre. Admire this magnificent resurgence with its wild but accessible character, climb up high, follow the Bayard botanical trail and contemplate a grandiose and unusual landscape from the Belvédère de la Roche Fendue.

I suggest a lovely walk in the heart of the Jura, between Syam and the Chaux-des-Crotenay plateau, to a site of interest to archaeologists. There are two difficulties to note: access to the Belvédère du Rachet and the short crossing of the Grotte de la Grande Cheminée. The rest of the route is not difficult.

Forest walk in the hills above Syam to discover the Grande Cheminée, an open-air cave that was visited in the Bronze Age. An axe made of this metal was found there. According to some, you may be walking on the lost site of Alesia as you make your way to two viewpoints over the wild Saine valley.
