(S/E) Departure point: Place des Combattants d'Afrique du Nord in Thann, at 3 Rue des Jardins, signposted on the wall.
Take the small staircase at the top of the car park which leads to the Chemin du Staufen.
Follow this path for about 100 metres, following the red rectangle towards Staufen (Croix de Lorraine), and after the first house on Rue du Staufen, turn right onto the narrow, fairly steep stairway marked with a red triangle.
You are now at Staufen 510m, where there are benches offering a beautiful view of the Thann valley.
(1) Continue along the path marked with red triangles until you reach the intersection. Continue along the path marked with red rectangles and blue rings towards Place du Roi de Rome and the Plan Diebolt Scheurer and its shelter.
But before you reach the Plan Diebolt barrier, about 100m before it on your right, you will see an oak tree with six trunks.
(2) Then follow the middle path marked with a yellow cross to Baumann - Weierlé to find the Baumann shelter at an altitude of 726m, which was completely renovated in 2017.
(3) Take the blue-crossed Baumann trail to the Teufelsgrund pass.
(4) At the intersection, follow the red discs and green rings, then the blue triangle towards the Zuber viewpoint.
Superb view of the Grand Ballon and nearby chalet, but not always open.
(5) At the chalet, continue downhill following the blue triangle and red disc signs towards Thann Riegelsbourg. Go around the mountain to return to Thann Steinby and not towards Leimbach. Please note that the red discs have been replaced by green ones.
(6) At the tennis courts, turn right onto the path with the red sign and blue cross towards Thann. To return to the car park, take Rue du Steinby, then turn left onto Rue des Jardins (S/E).
