The trail starts in the village, with a steep climb for a few hundred metres, then continues on a narrow path. Once you reach the hamlet of Villeneuve, most of the climb is done! 
Then you follow a small lane to the hamlet of L’Hôpital, before taking a sandy track that leads you to the Pont du Tarn. The last part of the trail is on the GR® long-distance hiking path, a pleasant route that runs alongside the Tarn. The first section of the descent is a little technical but also magnificent. The last two kilometres are identical to the first two.
 
Follow waymarks for #23.
