Trip Planner: Europe / Italy / Friuli Venezia Giulia / Province of Trieste / Sgonico / Grotta Gigante
The largest naturally occurring cavern in Europe, Grotta Gigante was discovered in 1840 during a search for underground water sources for the town’s aqueduct. Take a tour, available in Italian or English, and head down the 500 steps, past ancient stalactites and stalagmites, stopping to take in the views. After the tour, visit the nearby museum of speleology to learn more about the formation of the caves and see some interesting geological and paleontological finds, as well as a poster collection depicting the cave.

la grotta è davvero enorme e spettacolare, (la discesa un po difficile perché gli scalini sono sconnessi e scivolosi per l'umidità) un luogo unico nel suo genere per dimensioni e va assolutamente visi... more »the cave is really huge and spectacular, (the descent a little difficult because the steps are uneven and slippery for moisture) a place unique in size and must be visited. But even in the summer IT'S COLD inside so it is the case to dress appropriately. interesting explanation of the Guide, but I could not hear completely because of a girl who wept terrified (the acoustics greatly amplified every sound Cave) in short: don't bring the kids of 1-2 years, will surely have fear in such spaces
Eine Atemberaubende Höhle. Warum es aber nur drei Sterne gibt? Die Führung auf Deutsch ist nicht ganz so gut. Man wird durch die Grotte geschleußt wie Touristen.
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.
It's a wonderful big room very interesting. On the entrance there is a very nice museum
nice experience to watch the biggest hall cave in Europe and is very deep to and they used this place to detect earthquake signals
Amazing place well organised and guides are full of information.
