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. Pass the inclined plane on your right and head up to Saint-Louis.
The start is at the Saint-Louis picnic area. Coming from the funicular, enter the village, continue straight on past the church and take the first street on the left (Club Vosgien sign on a wall on the right). Walk down to the picnic area. There is space for 3 to 4 cars. Otherwise, park further up in the village.
(S/E) Walk down the track to the crossroads and take the track on the left, following the hairpin bend. Make a circular loop to the right and rejoin the path at the crossroads.
(1) Leave the track and head down the path on the right which leads to the shelter and the Fontaine des Trois Bacs.
At the Trois Bacs, continue downwards following the markings. The path winds along the hillside beneath rocky outcrops. Keep a close eye on the terrain, as the markings are not always very clear. Reach the stream’s valley floor.
(2) Stay on the path to climb up towards the 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 beneath the rocks.
The second time, the direction of the arrow is unclear. Do not head straight 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 round the rock hollowed out by a small cave. There is a bench here where you can rest. Go back a little way and head up towards the track.
Take this to the left, ignoring the signposting heading to the right, and follow it. You will rejoin the stream’s valley floor.
(4) Continue along this track to return to the first junction. Please note that this section is not signposted.
(1) Follow the route you took on the way out to return to the car park (start/finish).
