  • I visited the cave giant by buying a coupon on Groupon that allowed us to know this natural place full of spectacular story at an affordable price for my family (20 euros 2 adults and 2 children). The guided tour lasts about an hour. In all, about 1000 steps but you like doing and admire the stalactites and stalagmites that surround the path. My 4 year old daughter made them without complaint. Very nice guide, prepared and careful drove us together with a group of about 30 people to discover the wonders of nature underground, explaining in detail the origin and evolution of the cave. Recommend a visit, we were on holiday in Bibione and spent an afternoon out at the beach.

  • Is a beautiful natural site even if placed in an absolutely anonymous outside the city. The directions are easy to follow and is convenient then to visit coming or going from the city of Trieste. The visit is led with passion by guides (in our case, passion and love for the site). The view is changing and wonderful climb during descent. Trouble don't go there if you visit Trieste.

  • Fantastic from all points of view: the size, the stalactites, stalagmites, colors ... a unique show! Worth every single step (and there are many!) who go along to visit. Congratulations to the guide who escorted us: on time and ready to respond to the questions of us tourists with competence and kindness.

  • Must see place when you are in North East part of Italy. Very interesting place. You shouldn't be worried about steps. Toor is guided at low pace.
  • Well worth the trip. Tour guides speak Italian and English, so great for tourists. It's a steep 500 steps each way, so wear comfortable shoes (the tour guides are very patient if you are slow.)
  • Incredible caverns with a well narrated guided tour. Difficult to get to using public transport (buses are frequently off schedule). Really beautiful and well maintained trails down into the mountain. Bring walking shoes, there are plenty of steps! Tour guides do a good job of pacing the group for those who need more time going up and down.
  • Amazing!!! This place is a must see, photos don't do it justice. The tour guide was great and spoke really good English. She explained everything and was really informative. Thank-you for the wonderful experience!
  • The word SURPRISING is the one better describe the way this unique place makes you feel.
