Start and finish at the car park of the Imsthal Inn, accessible by car or bus.
(S/E) With your back to the inn, turn right onto the path, then turn right again after 150 metres, continuing straight on past the two tracks you come across, until you reach a path coming from the left.
(1) Follow this path. Take the first path on the left, ignoring a path on the right and then another on the left.
(2) When you reach the T-junction, turn left then right to join the road (elevation 370).
(3) Cross the road and continue straight ahead for 30 m. Turn left for 100 m until you reach the junction, then keep to the right and continue until you come out onto a forest track not far from the Rocher de Hirshfels. Cut across the track towards the rock. At the crossroads, go straight ahead to reach the rock.
(4) Enjoy the view from an altitude of 383 m. Return to the crossroads and turn right. Carry on straight ahead until you reach the panoramic viewpoint at the Rocher du Loosthal.
(5) Enjoy the view and resume the route. Keep to the right when you reach the road, then turn left to follow a path leading onto another road; turn right here to rejoin the departmental road.
(6) Cross the road and continue along the path furthest to the left. You’ll come to a large parking area; take the path on the right. Keep to the right all the way to the departmental road. Cross the road and you’ll arrive at the Rocher de la Grenouille.
(7) Turn left until you reach the next road, Chemin du Kirchberg. Follow this road to the right, keep right at the junction and stay on this road, which bends 90° further on. Pass the Kirchberg retirement home by 100 metres, and you’ll reach a fork in the road (elevation 384).
(8) Turn left onto Rue du Rebberg. At the end of the street, turn left (Le Kirchberg) then follow a path on the left leading back to the D7. Turn right onto it for 40 metres until you reach the Petote-Pierre post office.
(9) Just before this, turn left onto a footpath, then continue straight ahead onto a track. Keep going straight on until you reach a pond on your left. Pass it and turn left. Then keep to the right at the next three junctions, heading south-west. You’ll come to a tarmac road; follow it to the left until you reach the Auberge d’Imsthal and its pond. Return to the car park (S/E).
