The quarry is a place managed by a local association that organizes outdoor shows. In a bucolic setting, it is a real green setting in the heart of an old quarry. An atypical place that is worth the detour!

Offering both exceptional views from its slopes and a large, enclosed and very isolated space inside, it is a picturesque location near a tourist intersection. This hill dominates the surrounding valleys by about thirty meters.
