Great cave, huge, excellent guide, also in English. The prices are very reasonable for such a place. The whole guided tour lasts about an hour. If going during summer, don't forget to wear long sleeves because it is chilly in there!

A huge cave (supposedly the St. Peter church of Vatican City gets inside!), not a lot of stalactites/mites, but still a nice one hour tour in Italian an English.

The cave is fabulous but customer service needs working on. When you arrive you are given a page in your spoken language. We were given a page in English. That’s really all you need. The tour is frustrating as it’s all done in Italian. The...More

Very good and magnificent caves. It is very deep - and a flight of 500 stairs down and up the cave are the only way in and out. The guided tour was great. The group was very big and the big crowd of German kids...More

The Gulf of Trieste is just like a wind tunnel, and it is often rainy over there. In the very heat of summer days or in those windswept ones it’s a perfect choice to visit the Giant Cave where the temperature is always 11C. The...More

Made a visit with the family and attended twice the November run through the cave - Cronotraversata del Maestro - over the 500 steps down and the 500 steps up. Till 2006 it was declared the biggest cave in Europe. Recommended.
