Ventajou walks

From Notre-Dame du Cros (Caunes-Minervois), a route takes you to former marble quarries, with a picnic stop at the renovated Ventajou refuge, near the ruins of the castle of the old village that has disappeared. On the way back, you pass by the Moulin de Biot, a former witness to a technique of using wind energy for sawing marble. Warning from the author of the route in the "practical information" tab (2/11/2021)
