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.

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.

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.

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.

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.

Eleventh stage of the Échappée Jurassienne. Although relatively short,this stage is a veritable festival of natural sites, each more incredible than the last. It begins with the Hérisson waterfall trail, a refreshing escape along a picturesque path dotted with 31 waterfalls and 7 cascades, revealing breathtaking panoramas where the water flows majestically in an aquatic ballet. You then continue your journey by entering the Haut Jura Regional Nature Park via the plateau of the seven lakes. To round off this day full of discoveries, from the Pic de l'Aigle and the Belvédère des Quatre Lacs, you can enjoy not one but several breathtaking views of four of these turquoise lakes: the lakes of Ilay, Petit and Grand Maclu, and Narlay. Dominate the whole scene from the Pic de l'Aigle and the Belvédère des Quatre Lacs... There's no denying it, this stage is spectacular!

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!

A short hike between forest and lake, very peaceful and relaxing in this popular lake region.

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.

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.

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.

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.

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.

This balcony trail offers breathtaking views of the turquoise waters of the largest natural lake in the Jura. Surrounded by mountains, forests and rivers, the lake is an invitation to linger and discover the secrets of the woods...

A lord had three daughters of marriageable age. Capricious, they found all suitors unworthy. Annoyed, the fairy Melusine turned them into stone statues. Erosion has destroyed two of these gossips. Time will get the better of the last one, so don't delay in paying her a visit. On the way, you will see the ruins of a castle perched on the cliffs, views of the Val de Sirod, and picturesque stony paths winding through beautiful rocks. Return via the Perte de l'Ain and its superb gorges.

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.
