Bélvédère des Quatre Lacs walks

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.

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 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.

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.

The Échappée Jurassienne is an invitation to discover, step by step, the striking diversity of the Jura Mountains. This 15-day itinerary links the west to the east, from the plains to the mountains, crossing the unspoilt landscapes of the Haut-Jura Regional Nature Park, far from the borders and close to the essentials. From the peaceful canals of Dole, the trail winds its way through the most iconic sites of the Jura: the Cirque de Baume, lakes, remote valleys, viewpoints and deep forests, before ending majestically in Saint-Claude, a town nestled in the heart of the mountains. Over the course of these 311 km, this itinerary becomes much more than a hike: it is a true distillation of the most exceptional things the Jura has to offer. The richness of the landscapes, the contrasts in altitude and the authenticity of the villages you encounter allow everyone to surpass themselves, immerse themselves fully in the wild beauty and reconnect with the essentials.

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!
