Access from Saverne: follow the Zorn valley to Lutzelbourg via the D132. Turn left onto the D98 towards Dabo. After the Lehrer crystal factory, turn right onto the D97b. Leave the inclined plane facilities on your right and climb up to Saint-Louis.
The starting point is at the Saint-Louis picnic area. Coming from the inclined plane, enter the village, continue straight on after the church and take the first street on the left (Club Vosgien sign on a wall on the right). Go down to the picnic area. There is space for 3 to 4 cars. Otherwise, park higher up in the village.
(S/E) Go down the path to the crossroads and take the carriage road on the left, turning sharply. Make a circular loop to the right and rejoin the trail crossroads.
(1) Leave the track and go down the path on the right which leads to the shelter and the Fontaine des Trois Bacs.
At Les Trois Bacs, continue downhill, following the markings. The path winds along the hillside beneath rocky outcrops. Pay close attention to the terrain, as the markings are not always very clear. You will reach the stream valley.
(2) Stay on the path to climb back up towards Rocher du Calice. There are two points where the markings are unclear, both in hollows.
The first time, the path seems to disappear. Climb up to the left via a few steps, then follow to the right under the rocks.
The second time, the direction of the arrow is unclear. Do not go straight ahead into the valley, but turn left. Cross a small stream via a footbridge, then take the steps on the right.
(3) Continue for about ten metres to go around the rock hollowed out by a small cave. There is a bench where you can rest. Go back a little and climb up to the carriage road.
Take it on the left, leaving the signpost on the right, and follow it. Return to the stream valley.
(4) Continue along this carriage road to return to the first crossroads. Please note that this section is not signposted.
(1) Follow the same route as on the way out to return to the car park (S/E).
