Park in the small car park in the woods, near the intersection of the D134 and D7 roads connecting La Petite-Pierre to Rothlach.
(S/E) Join the D7 and turn left to reach the entrance to the village of La Petite-Pierre.
(1) Take the path marked with yellow diamonds that descends to the left before the pharmacy. Be careful, as it can be slippery for a few metres. Follow these markings along a shaded path. At the crossroads, turn left to reach the Imsthal inn.
(2) Just after the inn, take the path that climbs to the right, still following the yellow diamond markings. You will reach a four-way crossroads.
(3) Turn left, almost 180°, onto the path marked with a yellow ring and red cross. Follow this path to reach the crossroads at the Loosthal Forest House.
(4) From the car park at the Loosthal forest house, follow the path opposite that heads left towards the Maison Forestière du Vieux Hêtre, marked with blue rectangles, blue easels and red triangles, until you reach the starting car park (S/E).
