  • Definitely the largest open area I've seen in a cave. It's overwhelming to enter this huge open space that is completely under ground (as with any cave, of course) and especially to descend to its bottom and then up again. A wonderful experience and a great guide! We had a nice technical discussion and we got interesting details about the earth, not just this cave. Great job!
  • Highly recommend this cave, it is ENORMOUS. Our guide was very knowledgeable and gave the tour in Italian and English. 👍🏽
