Col de l'Aiguillon walks

Stage 5 From Les Rousses to Lake Constance via the Jura ridges. From Sainte-Croix, the birthplace of music boxes and automatons, you set off across the vast pastures of the Vaud Jura towards La Casba and Les Avattes. The path then winds its way to Les Petites Roches before reaching the mysterious Pierre de la Paix, a place full of energy and serenity. One last effort takes you to the summit of Chasseron, at an altitude of 1,608 metres, where a magnificent panorama opens up over Switzerland and France. At your feet lie Lake Neuchâtel and, further south, the majestic Lake Geneva. Nearly 250 kilometres of Alpine ridges stretch out on the horizon, creating a breathtaking natural fresco. The descent is gentle to the hamlet of Les Rochats, at the start of the Les Cluds cross-country ski trail, where an old military barracks remains, a discreet witness to a forgotten past.

The Gorges de l’Orbe offer magnificent scenery in all seasons. This route, on the left bank, is better suited to the wetter months than the one on the right bank. There are no major difficulties, but some downhill sections can be tricky if you’re walking after rain, with mud and a risk of slipping. Walking poles are not a bad idea, which is why I’ve classified the route as of medium difficulty This route partly overlaps with the Gorges de l'Orbe route featured on the website.

For this fourth stage, after a good hour's walk, you will reach the highest point of the day: the Dent de Vaulion. The lakes of Joux and Brenet will be at your feet. The water from these two lakes flows underground, shaping the karst cave of the Orbe, near Vallorbe. On a clear day, you can see up to eight lakes.

Stage 3: From Les Rousses to Lake Constance via the Jura ridges. From the beach at Lake Joux to Le Pont, you reach Vallorbe via the Dent de Vaulion (1,483 m) before following and crossing the River Orbe. Since the Middle Ages, Vallorbe has been an important centre for the iron industry thanks to its iron ore deposits and wood reserves. At the Vallorbe Iron and Railway Museum, you leave the town following the shore of Lake Day. The route then passes close to the Day Viaduct, a beautiful arch bridge built in 1925, before arriving at the Day Dam, which holds back the waters of the Orbe, and then Ballaigues, located on the southern slope of the knoll, above the course of the Orbe

During this fifth stage, you will reach the highest point of the Swiss Jura and also of this 6-day route: Mont Tendre. This summit offers a splendid view of the Vaud region, Lake Geneva and the Alps. You will also see numerous "murgers" stretching for miles. These are stone walls built to mark the boundaries of plots of land or enclosures for grazing animals.

The goal for this second stage is to climb Chasseron. This rocky cliff offers breathtaking views of Lake Neuchâtel and, further south, Lake Geneva. You will also enjoy views of numerous Alpine peaks in the distance, rising up from the horizon.

Sixth stage, from Les Rousses to Lake Constance via the Jura ridges. From Les Rochats, the route climbs gently through pastures and wooded areas. You then arrive at the impressive Creux du Van rock cirque. From the heights, the view of Lake Neuchâtel is splendid. Then, taking the Sentier des Quatorze Contours trail, you descend towards Noiraigue, surrounded by two natural wonders: the Creux du Van rock cirque and the Areuse Gorges.
