Col des Étroits (1152 m) 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 highlight of this third stage will be the Suchet. At your feet, you will enjoy a panoramic view of Lake Neuchâtel. You will also be very close to the French-Swiss border. In Vallorbe, you will notice the presence of old railway crafts.

Stage 4 From Les Rousses to Lake Constance, via the Jura ridges. From the southern slopes of the Knoll, above L'Orbe, the climb to the ridge offers a magnificent panorama: Lake Neuchâtel, the plain and the Alps in the background. The trail crosses the peaceful pastures of the Jura before reaching the Col de l'Aiguillon, close to the French border, marked by anti-tank obstacles and bunkers. The hike continues along the Crête des Aiguilles de Baulmes, lined with 80-metre cliffs, with breathtaking views of Mont Blanc, Lake Geneva, La Dôle and Chasseral. The descent leads to Sainte-Croix, renowned for its music boxes and automatons.

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.

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.
