  • A magical place, an entirely different world. The depth of the cave is about 120 m under the ground down lead 500 degrees, and then upstairs almost as much. But the place is worth it! Many giant stalactites and stalagmites, age thousands of years.

  • It's better to know before. To admire one of the largest caves in the world take 500 steps downhill and to the ski lifts. But it's worth it. The visit is made at each on the hour and you are accompanied along a staircase, by a guide who explains the history and the current scientific use by means of equipment located on the bottom. The environment is characterized by stalactites and stalagmites, not so fascinating as Frasassi or Castellana, but are the dimensions that make it unique and impressive. To see. At the entrance, before declining, a little Museum where is told the history of the place. On the way out, you can eat in the nearby and only restaurant-bars in the area. The giant cave is easily reached by bus 42 from piazza Oberdan.

  • Sensational and impressive Grotto. Good driving that detailed descriptions of the place (the guide speaks in English and in addition the cave features speakers who translate in German!!!) Recommended with comfortable shoes and with the knowledge of having to face a long descent and a beautiful staircase to climb. The Council for a look into the ground, it's not every day be 100 meters below ground. ;-)

  • 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.
