Grotta Gigante Pendulem Trieste Italy

Grotta Gigante Trieste

Grotta Gigante, or Giant Cave, is one of the best caves in Europe. It’s gigantic natural cavern space makes Grotta Gigante a definite Trieste must see. Until 1995 it was known as The Largest Tourist Cave in the World, a title it lost in 2010, with the opening of La Verna Cave in South-West France.

The size of the cavern is what makes Grotta Gigante so special. Walking down, down, down into the semi-gloom gives that spooky “journey to the centre of the earth” feeling. After 80 metres of descent the area opens up into the impressive Giant Cave. Plunging down the centre of the cavern are two rods of a geodetic pendulum that monitor techtonic movements of the Earth. They alone have recorded four out of five greatest earthquakes in the recent 50 years.

The steps are even and easy to walk on, but it’s probably best to wear joggers.

First explored in 1840, the cave was fully mapped in 1897 and first opened to the public in 1908. It wasn’t until 1957 however, with the introduction of electricity to the cave, that tourism took off.

This is karst country where rivers run underground and those first cave explorations were an attempt to find water to plan Trieste’s aqueducts. Other karst country we learned about later in this trip were Plitvice Lakes and Krka National Park in Croatia and the Trebisnjica River and Neretva River in BiH. Karst Country is special!

Stalagmites grow 1mm every 15 years!

The descent into the cave is via 500 stairs with another 500 on the ascent, creating a total distance walked of 860 metres. Steps aren’t one of my favourite things, but these didn’t seem exhausting at all. The group stops to listen to the guide in several different languages, leaving plenty of time to catch your breath.

Perfect for Pinning.

The statistics of the chamber are 107 m (351 ft) high, 65 m (213 ft) wide and 130 m (430 ft) long.

Guided tours operate every hour for one hour. Our guide spoke English, Italian, German and probably more, but it might be an idea to ring ahead to make sure which tours are given in English. Arrive 15 minutes early, to purchase tickets and peek at the museum.

The Stalagmites, the tallest of which is 12 metres, have a knobbly appearance due to the drops falling from a height of 80 metres.

    We could see Trieste from Koper in Slovenia when we were there. I never knew these caves existed. They are extraordinary. They remind me a little of Surprise Caves in Halong Bay, Vietnam.

      Underground is a whole other world isn’t it Kathy. At Koper you were very close to Piran (my favourite Slovenian coastal village) and Trieste is quite pretty too.

    Absolutely stunning shots but I am afraid I couldn’t have gone in there to take any. . .too close a quarter’s for me. Most interesting post though as I don’t think I’d ever heard of it before!

      I’m happy to hear you say that cave photography can be difficult Krista because I thought our photos could have been better.

    Wow, this cave is stunning. It is the first time I heard about it. The different lights are so well placed. They illuminate the formations in a stunning way. We have a karst area in Puerto Rico. Many years ago, I went on a excursion that visited 4 caves. We also have a big “park” open to visitors (Cuevas de Camuy).

    I’ve been in Carlsbad Caverns which I thought was rather big, so this place must indeed be gigantic if it’s the world’s 2nd biggest tourist cave. Wonderful photos! The last time that I was in a cavern, it was so dark that my photos came out blurry. I see that Grotto Gigante doesn’t like tripods.

      Their website says that Michele but if they weren’t busy they might allow them. Probably worth asking.

    Thanks for introducing this to me.. This is the first time that I have heard about this underground cave considering that it used to be the world’s largest tourist cave.. By the way, your photos are amazing.. They are bright, clear and the colors came out perfectly.. Hope to visit this place someday..

      Thanks Maria. Caves are difficult to photograph so I’m flattered. Half of the photos are my husband’s and half mine. 🙂

      I’d never thought about caves in Europe before, but I guess there is a heap of them, especially in Karst Country.

    This is beautiful! I love caves and haven’t heard about this one. 500 steps up and down is a lot. What a fabulous job with the photos inside the cave and limited time.

      Thank you Mary. There were a lot of steps but it didn’t seem too many at the time.
