  • Vist the guide who explained the discovery and origin of this large cave. It is suggestive to spend some time in the "bowels" of the Earth!

  • And a very large cave. Are 500 steps to descend and 500 to climb. The temperature was great, around 11 degrees Celsius. To visit in any season

  • Many steps but so worth it. The cave is exceptional in size impessionanti. A beautiful now and say that the steps are many but they're our children aged 7 s 10 without complaint. Fair price for a good experience. I recommend it to everyone.

  • 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.
  • The scale is just unimaginable. Very special place. Glad we could share this moment with our eight year old. I would come to Trieste again just to see this magnificent Grotto! The guide was lovely too!
  • I have been here several times because I live in Trieste. I would definitely recommend to stop by because it is seriously HUGE and beautiful!
  • Huge cave. You have to do a lot of steps but it's amazing
  • Very interesting cave, not so long nor big, but I can stills say I liked it.
