A walk for experienced hikers to discover the area's geological treasures. Rocher de la Marbrière is a rock named after a deposit of high-quality marble that used to be mined there. This site once had a sort of bottomless crater. Unfortunately it was filled in during forest work in the 1970s. Today, the marble deposit is barely visible.
