Park at the Col de Shirm on the D14B4 (Route Joffre) between Masevaux and Bitschwiller-les-Thann.
(S/E) From the Col de Schirm, take the Chemin de la Bildbuche, indicated by a painted wooden sign, as you will find others during this walk. Follow the red and white rectangle markings towards Rossberg via Sattleboden.
(1) Leave Chemin de Bidbuche on your right and continue to the left, staying on the path marked with red and white rectangles.
(2) Join the Sattelboden path on the right, indicated by its wooden sign, and follow the red rings towards Sattelboden/Hirtzenstein to the Sattelboden pass.
(3) Leave the red and white rectangle markings and continue left on the path marked with a red disc.
(4) Leave the wide paths to begin the climb to Rossberg, via theGR®532, yellow rectangle to the right. Don't miss stopping at the old Sattelhütte farm for its fountain and the view towards the Ballon d'Alsace.
(5) Just before and behind the farm, leave theGR®532by turning right to follow the direction of Rossberg via the path marked with red and white rectangles.
You will soon leave the forest and reach the stubble fields. Walk straight ahead for a good hundred metres before turning right at the fence onto an unmarked path, which you will follow southwards to the summit marker.
(6) After enjoying the scenery, descend from the summit by following the fence eastwards. During the descent, don't miss the beautiful views of the villages in the Thur valley. Turn right at the junction with theGR®5marked with a red rectangle.
(7) At the junction with the red and white rectangle that climbs to the summit of Thanner Hubel, turn right and follow the red rectangle markings to the Col du Hunsdruck (south-east).
(8) When you reach the pass, cross the busy road carefully. Head right and begin the descent towards Bourbach on the path marked with red and white rectangles. This avoids the road, although you will have to cross it twice at the hairpin bends. Be careful when crossing the road, as the trail is not very well marked and you sometimes have to climb over the safety barrier. Continue to follow the red and white rectangles that lead to the Col de Shirm.
(9) Enter the village of Bourbach-le-Haut via Rue des Rochelles, passing in front of the church and then the town hall.
(10) Opposite the town hall, the trail takes a small staircase that appears to enter private property. Turn right immediately behind the hedge, walk along the house and continue on the trail to reach Route de Bourbach-le-Bas (D37).
(11) Just before leaving the village, turn right onto Rue du Schirm. Stop at the educational orchard, then a quick climb will take you to the pass (S/E).
