Hiking trail to climb the Grand Ballon - trail or hike

The route starts from the Place Clémenceau in Willer-sur-Thur and then goes to the campsite, passes behind the ponds and leads to the place called "Le Moulin" before going up to Goldbach.
In Goldbach, under the church, the route bypasses the village on the right and crosses the road to take the field road and a steep path that leads to the Hohneck on the village heights. The trail then winds through thatch and down to the village of Altenbach. The race takes the wide path that leads to the Sattel and then to the Ober-Sattel. The trail leads out of the forest at the Haag Pass and climbs to the summit via the right and the southwest balcony. After the stairs and the passage near the Blue Devils monument, the route turns right and leads downhill to the parking lot of the Grand-Ballon chalet-hotel and the finish line.
Please note that from the beginning of May, a temporary marker will be put in place to allow all those who wish to come and train on the World Cup course.
