The Caves of Oliero, karstic caves located in the common of Valstagna, originated thousands of years ago by the force of water coming down from the Plateau of Asiago, which has carved these deep rocky gorges to then emerge in the valley near the river of Brenta.

There are four caves open to the public, immersed in the greenery of a natural park: the two lower ones are the spring of the river ofOliero, while the two upper "covoli" with the ancient springs of the same streams are now dry. During a boat trip of about 30 minutes you will discover all the secrets of this underground world. A particularly impressive performance is offered by the casting room, a cascade of alabaster fourteen-feet-high stalactites, which enchants with the variety of shapes and shades.
