A walk for experienced hikers to uncover 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 here. This site once had a sort of bottomless crater. Unfortunately it was filled in during forest work in the 1970s. The marble deposit is barely visible today.
