The Caves of Oliero tourist complex in the amazing Nature Park takes you along a path through a lush green landscape to two dry caves (Covol dei Assassini and Covol dee Soree) and, heading down to the lake formed by the Oliero springs, it ends where you board the boat for a trip into the main cave (Covol dei Siori), where you can admire stalactites and stalagmites that are more than 40,000 years old. Besides caves and a picnic area, the Nature Park also has the Alberto Parolini Speleology and Karst Museum and the Papermaking Museum, which are free to visit during opening times.
