Caves of Oliero Natural Park

the garden

The fantastic underwater world of water, carved into the rock and set between two majestic mountains: the Sette Comuni plateau and the Monte Grappa massif. Immersed in the nature of Valbrenta, you will live an unforgettable experience in what the famous writer George Sand called an earthly paradise. more

the visit

Inside the complex of the Grotte di Oliero, four caves can be admired: the main one called the Covolo dei Veci and the Covolo dei Siori, which can be visited thanks to a small wooden boat that allows you to reach, accompanied by expert guides, the belly of the mountain, between stalactites and stalagmites that provide the backdrop for an enchanted realm. The other two caves, which can be visited on foot and located above the others, keep the memory of the flow of water in ancient times. In addition to the caves, it is possible to visit the natural park and the adjacent Speleology and Karst museums A. Parolini and the Paper Mills Museum. more


The Parolini family owned the whole area of the Oliero caves, and therefore the young Alberto Parolini had the opportunity to make here his exporations. For the abundance and constancy of the water that came out of the mountain and for the already known presence of a couple of caves, he hypothesized a rich and hidden underground water network. He worked to enlarge some cracks in the mountain, using dynamite, and in 1822 he was able to first cross the inner pond of the Covol dei Siori. It is indeed Parolini who gave the caves of Oliero their names, still used today: Parolini cave at Covol dei Siori, Cecilia Boune cave at Covol dei Veci. more
