Departure and return near the Phalsbourg-Lutzelbourg section of the Club Vosgien at Limmersberg (E 7°16'06 N 48°42'50) in Hultehouse (57).
(S/E) Head due east for 300 m.
(1) Take the forest road on the left for 400 m.
(2) At the crossroads, take the path marked by the Croix Jaune Vosges club. Follow this path, which runs alongside a forest road on a ridge marked with boundary stones dating from the 18th century. After 1.7 km, you will reach the Rocher du Muguet. Magnificent view over the Zorn valley.
(3) Descend into the valley, still following the Croix Jaune marked trail. You will come out onto the RD38 road. Cross it carefully.
(4) Cross over the Marne-Rhine Canal via lock no. 26. At the lock keeper's house, take the unmarked path that climbs to the right. Follow it until you reach the forest road marked with red-white-red rectangles.
(5) Follow it to the left for 300 metres.
(6) Turn onto the path that climbs up to your right, marked with a yellow cross. Follow this path for 1.8 km until you reach the Schweizerhof forest house and pass in front of it.
(7) Shortly after the meadow on the right, take the path on the right marked with a yellow easel.
(8) Follow the forest road marked with a yellow easel sign on your right for 2.2 km to reach the ruins of Greifenstein Castle.
(9) You can easily climb one of the castle towers, which offer magnificent views of Saverne and the surrounding area, including the ruins of Haut Barr Castle and Grand Geroldseck Castle.
Set off again along the path marked with a blue rectangle.
(10) After 1.3 km, visit the Saint-Vit Cave. Continue following the blue rectangle markings to the Rappenfels rock, 1 km away.
(11) The short detour to the rock is well worth it. Then descend into the valley.
(12) Cross the canal at lock no. 27, then the cycle path. Go down the embankment and turn left onto a small bridge over the Zorn.
Cross the RD38 and then the railway line, continue straight ahead for 400 m on the tarmac road.
(13) After the reservoir, turn right and follow the yellow ring markings on a tarmac road.
(14) After a bend and 860 m, take the path on the left along the hillside, marked with a yellow disc.
This leads to the Wasserwald plateau.
(15) The viewpoint is disappointing as the trees block the view. Follow the path marked with yellow discs. After a few hundred metres, cross the vast Gallo-Roman site of Wasserwald.
Continue along the same path for about 2 km to reach the starting point (S/E) near the Club Vosgien refuge.
