Grotta della Spipola
The Spipola cave, along with the Farneto cave, is one of the most important and spectacular attractions at the Parco Regionale dei Gessi e dei Calanchi Bolognesi. Discovered in 1932 by Luigi Fantini, who lowered himself into the cave from the famous Buco del Calzolaio, or "Cobbler's Gap", it is a route covering 500 metres popular with guided tours.
The tour is a true speleological experience that enables visitors to learn about the park's underground karst morphologies while passing through chambers, tunnels, alabaster beds, and ceiling channels, ending with a visit to the enclosed sinkhole.
