The visits are carried out with a guide, in groups, and last about an hour. The inside constant temperature is about 10 °C – 50 °F throughout the year, humidity reaches 90% in certain points. To make the walk pleasant it is useful to have suitable clothing and footwear.
A few steps from the atrium, there is the entrance to the Devastation Gallery, where the chaos of time prevails over the harmony of forms and imagination. Going along the main road you will reach the Aligi Room, where the constant work of water is clear. Water is the true protagonist of our journey within this wonderful and unique underground world. Water is director of forms, creator of wells, tunnels, underground lakes, and mother of stalactites and stalagmites.
At the end of the Aligi Room, we find ourselves in the presence of the Sentinels, formations of stalactites and stalagmites that greet our entry into the Main Gallery. From here on it is all a succession of limestone formations and fantasy form games. Here are a few names: Elephants Hall, Statues Hall, and Hams Hall.
