Departure from Klingenthal. Follow the D 204 Route de Grendelbruch.
The car park is located after the village exit, at the junction of the D204 and D616, on the right on Rue de Steinberg.
Signposting: Yellow disc
(S/E) From the car park, cross the D204 towards Heidenkopf, go to the concrete block opposite (pumping station) and take the path entering the forest.
(1) After 5 minutes, you will reach a small concrete building topped with an antenna. Continue along the path opposite.

Cross a forest road and turn left towards the south-east (signposting has been changed).

Leave the forest road and take the slightly uphill path on the right (north-west) (with your back to the viewpoint).
Further up, at a three-way junction, go straight ahead, heading west, and take the middle path.
Reach a small road and turn left then right to continue on the path opposite.
No signposts

(10) When you reach a paved road, turn left and then right to take a path heading directly towards Klingenthal.
(11) At an old wooden bench, leave the path and take a trail on the left towards Klingenthal via Wolfsgrube. The trail is located before a clear bend and the sign is old and not very visible.
(12) At a bend, pay attention and take a path slightly to the left, the start of which is not very visible: do not follow the path furthest to the left, but take a small path to the right. The blue sign is on the trees (do not follow the wide path going uphill opposite, which is not shown on the map - do not continue on the main path turning right).
Further down, at a forest path, turn left and then right to pass in front of a reservoir (source marked on the map).

After a bend, you will come to the intersection you passed at the start of the hike.
(2) Turn right and follow the same path you took on the way there until you reach the car park (S/E).

As I was only in the region for a short stay, I couldn't pass it up.
