In the valley of Laclaireau is partly caught the Valvert spring water. The walk begins with a beautiful overview of the tufa of Montauban. Don't fail to drop by the archaeological site just above the car park. An open air museum, the ancient fortifications' ruins and the installations of contemporary art will enchant your trip. The beauty of this walk lies in the diversity of the places that are crossed ; along the Big Stream, in the privacy of a pine forest and then of hardwood of pasture green.
