Gouffre des Busserailles

From Pâquier (municipal seat) take the paved road on the left that leads to Crépin. When you get to this hamlet, go past the chapel dedicated to Saints Crispin and Crispinian (with a fresco depicting the legend of Saint Theodulus and the devil), and at a crossroad take route towards Proz (1676 m). Continue along the same route until you come to Gouffres de Busserailles, a ravine that can be visited, 104 m long and 35 m deep, dug into the mountain by the force of the waters of the Marmore.
