The tour leads mainly on small and smallest roads, which are partly in relatively bad condition. There are many climbs and descents. The landscape is varied and impressive. A tour that emphasizes the beauty of this part of the Jura!

From Balsthal, the route first heads north over the Passwang. Uphill - hardly visible between two houses at the side of the road - a small road branches off to the right, which you follow to Nunningen. The route continues via Erschwil and Bärschwil - always on small single-lane roads. The tour leads via Kleinlützel to Roggenburg and via Ederswiler, Movelier and Pleigne to the Col de Rangiers. From there down into the valley to St. Ursanne - a very beautiful place to visit! From here along the idyllic Doubs to St.-Hippolyte and then about 15 km through the valley of the Dessoubre. Over a small, narrow bridge the path leads south. Via Battenans-Varin and Trevillers, one reaches the Col de la Vierge. The valley descent to Goumois offers some very nice views down to the Doubs. Afterwards, the path climbs again via Saignelégier and Montfaucon. From here via Soubey back down to St. Ursanne. The further way leads over the Col de la Croix (beautiful view of the Vosges mountains on the horizon!) to Courgenai and via Charmoille, Lucelle and Kiffis to Welschwiller. Further on via Laufen, Wahlen, Büsserach and Zullwil to Beinwil (again an extremely narrow and beautiful road!). From there it is not far back over the Passwang to Balsthal.
Total length 295 km
