Park in the car park behind the Jungholtz playground, in front of the old factory that has been converted into a first aid station.
(S/E) The trailhead is to the right of the old factory and a blue house.
Follow the signs for the Club Vosgien (yellow triangle) towards the Col de Bildstoeckle.
The trail climbs steadily up the southern slope. After 500 metres, you will pass a water tank. Continue climbing until you reach the Col de Bildstoeckle.
(1) At the pass, you will find a calvary and a multitude of trails.
Take the third trail on your left and follow the red-white-red rectangular signs towards the Col de Peternit.
(2) After about 300m, take the path that climbs steeply to the right and takes you up 60m to return to a flat path that you follow to the left to the Col de Peternit. Be careful as this path is not shown on the IGN map but is shown on the OSM map.
(3) At this pass, take the first path on your right and follow the blue triangle markings towards Rehbrunhenkopf. The path on the hillside will first take you to the small Col de Lindloch, then climb steeply along the municipal boundary (Vosges sandstone markers) to the summit of Rehbrunhenkopf.
(4) Continue down this path, still following the blue triangle markings, towards the Col de Bidstoeckle. The path turns left in a hairpin bend and heads north until you reach a forest track.
(5) Turn right onto this path, continuing to follow the blue triangle markings.
(1) At Col de Bidstoeckle, take the trail just behind the calvary. This trail climbs and follows the municipal boundary and the same blue triangle markings towards Nez de Soultz. You will arrive at the summit of Heidelberg.
(6) Continue to follow the municipal boundary and the blue triangle signs. The trail descends and passes through a flat area covered with heather (7), ideal for a break in the sun.
(8) When you reach Nez de Soultz, you will have a beautiful view of the town of Guebwiller. Follow the trail that turns right and heads south-west along the cliff, following the blue triangle markings until you reach the intersection. Then follow the markings towards Soultz (white and red flag) and finally follow the round blue markings towards Jungholtz.
When you reach a major crossroads, turn left. After a few metres, you will leave the woods and arrive in the vineyards.
(9) At the first crossroads, turn right and cross the vineyards, following the farm track.
This leads to a wood concealing a crossroads.
(10) Turn left to leave the woods and return to the vineyards. The farm track then arrives in the residential area of Jungholtz.
Once you reach the D51, turn right to return to the village centre and the car park at the starting point (S/E).
