Parking: Sandgrube fitness trail
(S/E) From the car park at the ‘Sandgrube’ fitness trail, take the forest track marked with a Red Rectangle crossed by a white bar until you reach the first junction. Turn right onto the path marked with a Blue Cross, then left onto the path marked with a Red Rectangle crossed by a white bar (forest track). Cross one forest track to reach another.
(1) Continue straight on, following the ‘Red Rectangle with a White Bar’ markings, along a forest track leading to Peternit Rosstall (549 m). Climb to the left to the Col de Peternit (566 m) via the path marked with a ‘Red Rectangle with a White Bar’.
(2) Carry on straight ahead twice, then turn right, following the southern slope, to reach Munsteraeckerlé (655 m): a picnic shelter.
(3) Follow the Red Rectangle with a white bar markings all the way to the Grand Ballon. From Munsteraeckerlé, veer sharply left then right onto the path overlooking the track and, approaching from the southern slope, climb to the Col du Judenhut (973m) via the Ebeneck. At the Ebeneck, cross the track twice. At the T-junction, continue to the left, then straight on to the Col de Judenhut, where you’ll find the Club Vosgien de Guebwiller shelter and the Schlumberger Fountain.
(4) Turn left then right and, via the southern slope, climb through the Belchenwald to the Grand Ballon. At the track, keep left, then turn right to cross a second track and then a path marked with a Red Diamond. After an old ski lift, turn right to emerge next to the restaurant La Vue des Alpes (1,341m). The Grand Ballon chalet-hotel, owned by CV Strasbourg, is situated above the Route des Crêtes. It is possible to climb to the summit at an altitude of 1,424 m via a path marked with a Red Disc or Red Rectangle.
(5) From the pass, turn left onto the Route des Crêtes, then take the Red Rectangle-marked trail on the left, which leads to the Firstacker (995 m) via the Grand Ballon farmhouse inn. Leave the tracks on your right, then cross the road at the Grand Ballon farmhouse inn. Further on, continue downhill, cross the road again and head to the next junction. Turn right towards the Firstacker.
(6) Take the second forest track on the left marked with a Red Rectangle crossed out in white. Ignore a track leading down to the left and pass through the Sudel and over the Diefenbach heights. Continue straight on at the next junction, then keep left until you reach the path marked with a blue triangle. Continue along the second track on the right and carry on straight ahead until you reach Rimbach via the Schwarzbach.
(7) Once you reach the D5.1, cross the road and head up to the Col de Peternit via the forest track marked with a Red Rectangle crossed out in White.
