Parco naturale delle Grotte di Oliero

The Oliero Caves comprise a network of underground chambers and passages formed by water erosion through limestone rock over millions of years.

The caves were first documented in 1804, leading to scientific studies that revealed important geological formations and underground water systems in northern Italy.

The park maintains a geological museum displaying mineral specimens, fossils, and educational materials about the cave formation processes and local environment.

Visitors can explore the caves through guided boat tours while wearing provided safety equipment, with tours departing regularly throughout operating hours.

The cave system contains Europe's deepest siphon at 135 meters, connecting to an extensive underground river network beneath the Asiago plateau.
