What to expect

Friuli Venezia Giulia is an area rich in karst areas, in which more than 6,000 caves develop, some of which reach extensions of several tens of kilometers and hundreds of meters in depth. These caves are a heritage of priceless beauty. The majority of these cavities are accessible only to cavers while others have been equipped and secured to allow everyone to visit them safely.

Explorer FVG reviews


Grotta Gigante

The Giant Cave consists of a giant hall nearly 100 m high, 168 m long and 76 m wide. In 1995 it was listed in the Guinness Book of Records as the world’s largest natural hall.


Grotta di Villanova

The Villanova caves are one of the jewels of Friuli, and a visit to the New Cave is an exciting and unique experience. Equipped for sightseeing, it consists of a 9-kilometer underground route, allowing visitors to enjoy an educational, adventurous and safe visit.


Grotte di Pradis

The caves and gorge of Pradis include a whole area to be discovered, where suggestive glimpses are concealed in every ravine, immersing oneself in a wonderful natural stage carved out by the waters over the millennia.


Cave St. John of Antro

Climbing the steep steps, going over the walls and discovering a church built inside a cave is fascinating. The guided tour also allows visitors to explore the cave behind an altar and learn about both the geological and karst peculiarities and the thousand-year history of this place.


Abisso di Vigant

The wide 15-meter portal immediately evokes the grandeur of Vigant Abyss, which is 252 meters deep and whose underground development is accessible only to experienced cavers. A wooden walkway with handrails allows for a safe visit to the entrance.


Grotte di Timau

Just above the source of the Fontanone di Timau opens the intricate tunnel system of the Timau Caves. The cavities are not natural, or are only partially natural, but date back to ancient chalcopyrite mine galleries.
