Postojna Caves, Postojna
(4.6/5 based on 3,200+ reviews on the web)
Ride on a double-track railway through the underground tunnels of Postojna Caves and see colorful rock formations, as well as the 100 species that make the caves their home. One of the largest caves in the extensive karst plateau features 21 km (13 mi) of passages, galleries, and chambers illuminated by electric lighting. A historical train takes you to large halls adorned with chandelier-like stalactites and limestone "sculptures," such as "the brilliant," a shiny white limestone formation. Meet the olm, a salamander popularly called the dragon's offspring or the human fish. Archduke Ferdinand I was the first to officially visit the cave in 1819, but several writings on the cave walls date all the way back to the 13th century. Note that audioguides are available in a range of languages.

  • What we could see was ok, train/tram went way to fast we didn't have time to get off and explore or take pictures. Our 90 min tour was only 40 min as train operator wanted to go to lunch. Huge disappointment for such an interesting place we paid a lot of money to see.,no refund offered when we complained either
  • 20 km of underground caves, really amazing, must see if you visit Slovenia Beneath the surface lies a wonderful subterranean world abundant with unusual sculptures and animals. And not far from the cave, above the surface, you can admire Predjama Castle and its surrounding area steeped in history.
  • Absolutely gorgeous cave beyond anything in the US and I've been to all the major commercial US caves. Excellent organization and tour. English guide was very good and answered all the questions. Sang a few phrases in Slovenian in the 'concert chamber'. Elegant voice and made the whole experience holy.
  • There's a good reason this is one of Slovenia's most popular tourist attractions - it's really cool! I loved the train rides in to and out of the caves. Our tour guide inside the caves was interesting and lively, which made it all the more enjoyable. If you're in or around Ljubljana, then you really do have to go and see this place.
  • HUGE and beautiful cave. A short train ride and you can explore inside the cave system. A fascinating place...great for all ages.
