Get ready!

As the name implicates, Postojna Cave is located in the town called Postojna, which is in the Karst region of Slovenia, some 60 km from the capital Ljubljana.

You can get there from Ljubljana with either a train or a bus. However, we would recommend you to take a bus since it stops much closer to the cave. It is useful to know that there are also buses  which stop almost at the entrance of the cave.

Meeting our guide at the entrance of the Postojna cave.

TAKE A NOTE:

  • Postojna Cave has a constant temperature of 8°C to 10°C with a humidity of 95%. So, warm jacket and decent shoes are advised in any season of the year.

  • The visits of the cave are guided. Which means you get to join a group based on a language of your preference (audio-guides are available in most international languages).

  • Of some 24 km long cave system, visitors get to see 5km of the cave on 1½-hour tours; part of the cave is covered by an electric train.

  • The visit of the cave proceeds on foot; the guides take the visitors through tunnels, spectacular halls and breath taking galleries with different sizes of the stalagmites, stalactites and nature made columns and pillars.

  • Taking photos is allowed, but no use of flash (strong light damages the surface of the cave formations).

  • Taking photos in the cave or selfies while on a electric train might be dangerous. Because of the narrow tunnels you are passing, by lifting hand above the head you can hit the wall.

Get amazed with the Postojna Cave!

By entering the Postojna Cave one cannot stop wondering how did all of this »happen«? What is the story behind this enormous underground web of tunnels?

Also, how were these fantastic and unique shapes and formations in which one can sometimes even recognize a familiar object, a face, a shape of an animal … made?

Oh, look, there is a bird, a dwarf, a beautiful folded curtain, even a diamond!

Pivka River – the creator of the cave

The main role in creation of the cave played the Pivka River. Over millions of years the river carved the numerous number of the underground passages, galleries and halls. Today the Postojna Cave is Slovenia’s most remarkable natural sight. Furthermore, it is one of the richest caves in the world in terms of cave formations.

The walk through the dark caverns is beautifully lit, so it feels a bit like being in an underground wonderland.

When our guide Vojko Jurca tells us that it takes 30 years to produce 1mm of stalactite (stalactites and stalagmites grow because of water running over and through inorganic material), his word strike me immediately – the cave is changing all the time!

Postojna Cave became officially known as a tourist destination in 1819, when archduke Ferdinand, heir to the Austrian throne, became the first person to sign the visitors book. At first, it was the guides themselves pushing along the rails. Railway tracks were laid in 1872 and the cave has been illuminated by electric lights since 1883, preceding even London.

Get to know the dragon

The caves are also home to the endemic olm or proteus, a rare and sensitive blind salamander living in the cave rivers of the region. The olm lives for more than 100 years but reproduces just once or twice a decade.

When in January 2016 one of the Postojna Cave guides noticed that there was an olm egg attached to the glass wall of the aquarium in the cave, Slovenia and the Postojna Cave immediately became main news. People around the world were eagerly waiting for the olm babies to hatch. From the end of May to mid-July 2016, twenty-two baby olms successfully hatched.

Sir David Attenborough, the legendary British naturalist and also author of numerous BBC documentaries, picked olms as one of ten endangered animal species that he would take on his very own “Noah’s Ark”.

Get more information about the Karst phenomena

As said earlier, the tour around the cave takes around an hour and a half. Further more, in the Postojna Cave Park there is much more to see besides visiting the cave. The exhibition EXPO Postojna Cave Karst (opened in April 2014) is the largest permanent exhibition about the cave and karst phenomena around the world.

Moreover, the visitors  can also learn about karst phenomena through projections of various material onto a three-dimensional model, discover the special features of the karst environment, and learn about historic events at Postojna Cave.

Also, don’t forget to check the Postojna Cave web site for package deals, including various combination tickets that include Vivarium Proteus, the new Expo and don’t miss Predjama Castle.

The Postojna cave also houses the world’s only underground post office.

TIP: Visit the nearby Predjama Castle

Additionally, to get to Predjama Castle (located approximately 10 km from the cave) you can use the organized shuttle bus, which operates during the high season – which is within the summer months. If you want to visit the castle outside the season, the best option to get there is to book a taxi. They charged us 10 Euro per person.

Send us an e-mail for further information about this option.
