    Nature’s wonder
    The cave is stunning yet somehow a little rough. It would be the perfect setting for a LOTR movie according to my children and I must agree. The guide is nice and informative though she doesn’t tell anything that isn’t written on the paper you get when buying your ticket. Extra points for having that in Danish too btw. Remember to book your time slot in advance.

    Very cool huge cave, great guided tour
    Truly an incredibly cool experience, a huge cave with lots to see and very beautiful. We had Christina as our guide and she gave lots of interesting information and was overall both funny and helpful. Though be aware there is a lot of walking, 500 steps down and 500 steps up.

    It felt like I was on a Lord of the Rings set
    The caves were just so cool! Much larger than expected. The tour lasted an hour and the guide was very knowledgeable. I learned a lot about stalagmite/stalactite formation which really rocks (sorry). I survived in shorts and t-shirt, though those of us who are not Canadian may want to dress up :)

About a 30 minute drive from Trieste is the Grotta Gigante. This is a truly unique, amazing, massive cave that photos don’t do justice to. Be aware that there are 500 steps down and then up. If one is fit, this is not a problem as the guides stop periodically going down and try not to hurry you going back up. If you have some issues with your feet, knees, or shortness of breath, etc. then it might be better to take a trip instead to Postojna Cave in Slovenia which has a train to take visitors around. In terms of impressive size, Grotta Gigante is well worth the visit if you can do the steps. From entrance into the cave to exit, the whole visit lasts just a little over an hour.

Amazing size and interesting. One hour tour well paced so 500 steps down and back up comfortable. Guide speaks on Italian then plays English audio which was fine for us.

Took the bus from the town centre" short walk to the caves. Don't be put off by the number of steps. The cavern is massive. The guide explained all the features with clarity and allowed plenty of time for slow walkers and photo taking. Worth it.

This huge cave is beautiful, uniquely large due to its location in the Karst and created by a river that used to run through it. There are hourly tours in Italian with brief summaries in English. The cost is 12 euros, though this is another one of those attractions that is free if you have the FVG card, which makes economic sense if you are staying several days in the region. You will go down more than 500 steps, the cave is well lit, the stairs and handrails are in good condition. The cave is constantly cool, a refreshing break on a hot day. You can get here by local bus from Trieste, the journey provides lovely views of the countryside and sea.
