Le Belchenflue (1099 m) walks

Twelfth stage From Les Rousses to Lake Constance via the Jura ridges. From Balsthal, the route begins with a steady climb to Roggenflue (998 m), offering a breathtaking view of the Swiss Plateau and two giants of the Jura: Mont Tendre and La Dôle. The hike continues through a majestic Jura beech forest, nestled between 600 and 900 metres above sea level, where the tranquillity of the forest accompanies your steps to Roggenschnarz. There, a spectacular descent awaits you: hundreds of steps carved into the slope lead you to the Wishöchi Pass. After this passage, a new ascent guides you to the picturesque hamlet of Bärenwil, before reaching the highest point of the stage: the Belchenflue (1,099 metres). The descent to the southern slope of the Solothurn Jura reveals a landscape steeped in history, dotted with concrete blocks, anti-tank obstacles and bunkers, silent witnesses to Switzerland's fortifications during the two world wars.

This exceptional hike links Les Rousses, in the heart of the French Haut-Jura, to the city of Constance (Konstanz), on the shores of the lake of the same name, following the ridges of the Swiss Jura. A demanding but magnificent 405 km route that crosses the most iconic landscapes of the Jura mountains: high-altitude pastures, deep forests, alpine viewpoints, villages steeped in history and forgotten military ruins.
