    The Pozzo D'Antullo is a large karst sinkhole, with a maximum depth of 80 m and a circumference of 300 m, originating from the sinking of the ground, due to karst phenomena in the area. The bottom of the sinkhole is completely covered by vegetation and there are curious curved stalactites, probably generated by the wind coming from the side tunnels that modify the deposition of limestone crystals. During the visit you can walk the entire perimeter of the sinkhole and admire it from different angles.
