The journey takes about an hour. The first room that can be seen is the Sala del Guano which until the 1950s-1960s was an ideal refuge for bats.
Going forward, the first stalactites appear, the stalagmites, the draperies that, thanks to the peculiarity of the carbonate rock combined with rainwater, have developed in enormous quantities throughout the cavity.
The Sala del Castello appears with its group of stalagmites reminiscent of an ancient medieval castle located on top of a hill. Then the route branches off into two cavities: we leave the main passage but crossing the adjacent siphon, we return to it later.
