You can start from Willer-sur-Thur station. This will also be the finishing point.
(S/E) Take the road that crosses the railway line, then take Rue de l'Antrain, which climbs through the houses. At the junction with the Thannerhubel ski lift sign, continue straight ahead, leaving the tarmac road to reach the entrance to the Willer-sur-Thur communal forest.
(1) A few metres behind the sign marking the entrance, take the path climbing up to the right, marked with a red disc, towards Rossberg via Blaufelsen. Follow these markings and this direction until you reach the Blaufels shelter. Join the Altrain forest path.
(2) Continue along this forest path, turning left. After walking for a long time along the path (more than 1.5 km), in a long right-hand bend, a path branches off to the right.
(3) Take this path up to the right, which joins a forest track.
(4) Cross the forest track and take the path ascending to the left. Continue south to the summit and the Blaufels shelter.
(5) Facing the Blaufels shelter, you will see a forest path descending to the left. Take this path towards Altrain, following the red ring markings. Follow these markings until the end of the route. After a right-hand bend, the path climbs back up to a crossroads of forest paths.
(6) At this fork, take the ascending path opposite. It quickly leads to Place Zundel.
(7) Continue along the forest path on the left, which is partially covered with tarmac. After a few metres, turn completely left onto the path leading down towards Willer-sur-Thur. After about 300 m, you will arrive at the Vogesapfàd Hisla shelter.
(8) Continue straight ahead, passing behind the shelter. The path heads east and reaches a fork in the marked paths.
(9) At this fork in the Willer - Bitschwiller paths, follow the path on the left towards Willer-sur-Thur. As you descend, cross the forest path and continue straight ahead on the descending path. Continue until you reach the starting point at the stadium and railway station (S/E).
