  • The giant cave is definitely worth a visit. Choose to visit it with the FVG Card and enter for free. A bit out of the way than in Trieste, is found on the nearby Karst. Don't forget a sweatshirt because you will get off at a temperature of 11 degrees with humidity of 97%.

  • Wonderful experience, very special and evocative cave for his greatness. Temperature 11 degrees all the way bring a sweatshirt.

  • the cave is really huge and spectacular, (the descent a little difficult because the steps are uneven and slippery for moisture) a place unique in size and must be visited. But even in the summer IT'S COLD inside so it is the case to dress appropriately. interesting explanation of the Guide, but I could not hear completely because of a girl who wept terrified (the acoustics greatly amplified every sound Cave) in short: don't bring the kids of 1-2 years, will surely have fear in such spaces

  • Eine Atemberaubende Höhle. Warum es aber nur drei Sterne gibt? Die Führung auf Deutsch ist nicht ganz so gut. Man wird durch die Grotte geschleußt wie Touristen.
  • The unexpected magnitude of the place along with its suggestive beauty, enhanced by a good use of artificial lighting made this visit a magic experience, for me. The ticket isn't cheap, but it's well worth it. The tour takes the better part of an hour, and it has many steps. The temperature inside is always cool so if you are visiting in the warmer months you should bring some extra clothing. Best thing to see around Trieste, in my opinion.
  • It's a wonderful big room very interesting. On the entrance there is a very nice museum
  • nice experience to watch the biggest hall cave in Europe and is very deep to and they used this place to detect earthquake signals
  • Amazing place well organised and guides are full of information.
