(D:A) The hike starts at Silber Thal Square (former St-Nicolas mine). Take the path heading west towards the Ste-Thérèse Chapel. The path leads to a forest track: take the path marked with a yellow triangle on the left. Follow this path for about 300 metres until you reach the Col du Amselkopf, a crossroads of four forest tracks.
(1) At the crossroads, take the first forest track on the right heading north, marked with a yellow cross, for about 400 metres. Please note that when the forest track turns right
(2), there is a small path just inside the bend that is difficult to see, which heads west and leads to the Saint Antoine Fountain. After passing the fountain, follow this path to the Waldkapelle (Forest Chapel).
(3) Cross the forest path to take the small path to the west (towards Thann), marked with a red and white rectangle. This path leads to a forest path at a hairpin bend.
(4) Continue along the forest track on the right and descend to Thann. Pass the large car park and continue along the tarmac road.
(5) Take the first right towards Col du Grumbach, heading north (signposted). Follow this path, marked with a yellow cross, to Col du Grumbach, a fairly strenuous 200-metre climb.
(6) Once you reach the pass, cross the forest path and take the trail that climbs towards the "camp des pyramides", marked with a red rectangle. This trail leads to a square called Place aux Canaries (altitude 674m). Cross this square and continue towards the Camp des Pyramides.
(7) There is a junction with a forest track: take this forest track on the left towards the Ostein farmhouse inn. Go straight down this track until you reach the junction with the path that leads to the Ostein farmhouse inn, marked with a red and white rectangle.
(8) There is a small sign indicating "difficult passage"; the trail passes through a scree slope but is very passable. Continue straight ahead, crossing a meadow to reach the Ostein farmhouse inn. After the farm, continue along the forest path, descending for about a hundred metres. At a T-junction (elevation 648), turn right.
(9) After a few steps, take the path marked with a blue triangle and a sign indicating "direct ascent to Rocher d'Ostein". The path climbs steeply to the east, joining a forest path where it turns south. Enjoy the view from Rocher d'Ostein.
(10). Continue along the trail towards the east to reach Camp Turenne. From Camp Turenne, take the forest path south for about 100 metres. On the left, there will be a small path marked with a red disc and a sign indicating the direction of Steinbach: go down this path, which leads to a forest track. Once on the forest track, turn left and follow the path.
(11) Turn right onto the small path marked with a red disc that leads to the Erzenbach Waterfall. Please note that the path is slippery in wet weather. Continue along the path marked with a red disc, cross a stream and rejoin the forest track.
(12). Take this path on the left, heading south, to the starting point (S/E).
