Le Frasnois walks

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

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.

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.

The Hérisson has a lot to offer! Its 7 waterfalls with 31 jumps: starter or dessert, depending on where you choose to start! A day to feast your eyes, literally and figuratively!

Magnificent waterfalls, among the most impressive in the Jura, whose reputation is well established. This walk leads to the foot of the torrent, which you follow to the summit, near the waterfalls and caves. It forms a loop, returning alongside the ridges, in the shade of a lush forest.

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.

A pleasant walk to do in a day. The trail runs either along the lake, overlooking it or along the edge of the rocks, with numerous viewpoints.

Pleasure in cascades. This extraordinary walk around the Pertes de l’Ain gorges sets out from the remarkable site of the old forges and is a delight for all the senses. Along the way: The Pertes de l’Ain, gorges, cascades, the ruins of Villain castle, and the relics of an old village.

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...

A splendid hike between the plateau and the steep-sided valley of the Ain. This circuit offers an opportunity to discover the upper Ain valley and its unique geology, with its Vaucluse spring, waterfalls (Le Moulinet, Saut des Maillys, Moulin-du-Saut) and ruined mills, evidence of how humans once harnessed the power of water. In fact, an EDF hydroelectric plant has replaced the old Moulin-du-Saut.

At the foot of the cliffs of the Risoux forest lies a patchwork of marshes and peat bogs. From the top of the Roche Bernard promontory, the small glacial lakes of Les Mortes and Bellefontaine are like jewels. An exceptional walk.

Through woodlands, forests and pastures, discoverthe Belvédère de la Roche Blanche, which rises to 1,013 metres, and admire the magnificent view of the Val de Mouthe (Doubs) on one side and the Val de Foncine (Jura) on the other.

Discover the splendour of France's third largest reservoir with its turquoise blue waters. In this magnificent setting, walk between forests and steep cliffs with superb views of the lake.

Without doubt, the shortest path up to the summit of La Dôle (1677m altitude) from the French side of the border. In good weather, the views are breathtaking and go on for over 250km: from the Swiss Alps to Mont Blanc and on to the Vanoise and the Ecrins, all of this with plunging views down over Geneva and its lake.
