Why should you visit Postojna Cave Park?

Postojna Cave is the largest show cave in Europe. It is located in the town of Postojna, in the Karst region, southwestern Slovenia. The cave is opened for visitors since 1818, and until this day it had nearly 40 million visitors! The Postojna Cave itself offers a 90-minute tour in the length of 5km. The tour includes a 3,5km long train ride and 1,5km long walking part. The Postojna Cave railway was the first railway ever to be opened in an underground cave!

 

The cave is also a place where you will see some of the finest examples of the karst formations. Stalagmites and stalactites are present in vast number, in all kind of forms and sizes. Another important value of this place is its fauna. The cave is a home to many endemic species. For example, the most famous of its residents is the olm, a.k.a. “baby dragon”.

But that is not all! The Postojna Cave Park includes a few more caves and exhibitions, an old mill, two castles, several restaurants, and a hotel! There is also a river and plenty of green area around the park, so it is a whole package deal for you and your company!

What to see in Postojna Cave Park

You might think that Postojna Cave is the only thing in the park that is worth mentioning, but you couldn’t be more wrong! There are many attractions inside the park, which can give you a full experience of the underground world and the entire Karst region.

Postojna Cave

For more than 200 years, Postojna Cave has been opened for public. It might not be the longest cave in Slovenia, but it sure is the most beautiful and the most famous one! Postojna Cave is actually a 24km long karst cave system, formed by the river Pivka millions of years ago. It is like a whole new world, only underground. It has its own mountains and rivers, vast halls and small passages, breathtaking cave formations, and the most interesting residents.

Some of the highlights of the cave are Brilliant – the five-meter-tall stalagmite called that because of its bright-white color; Skyscraper – the sixteen-meter-tall stalagmite, which is also the oldest one you will see; and the Calvary – a vast subterranean hall with a volume of more than 168 thousand cubic meters!

Vivarium

The Vivarium is located next to the cave and it consists of two parts – the research laboratory and the speleobiological exhibition unit. The exhibition offers a further insight into speleobiology and subterranean natural environment. Therefore, it presents the animal species that can be found in the Postojna Cave.
Among the 150 typical cave residents, the most significant one is the olm. This strange-looking animal is endemic to the underground waters of European karst region, which means it only lives in caves. Olm is blind and completely adapted to life in the dark. Because of its skin color, it is also called the “human fish”. It has a lifespan of one hundred years and can go without food for up to 10 years!

Expo Postojna Cave Karst

The Expo Postojna Cave Karst is a permanent exhibition held in a separate building in the Postojna Cave Park. The Expo was opened in 2014 and it is the largest exhibition about the cave and karst phenomena in the world. The exhibition is intended for those who are interested in getting a deeper insight into the underground world. Here you can learn all about the karst formations, as well as the history of the cave. The exhibition is guided and interactive, which makes it suitable for both children and adults.

Modrijan Homestead

The Modrijan Homestead lies on the Pivka river, inside the Park area. The homestead houses a mill, a residential building, and a restaurant. The Modrijan Mill has been turning its wheels for 500 years now, and it is free of charge for the Postojna Cave Park visitors. The mill also houses an occasional exhibition which tells a story of Karst region mills and the millers’ life.

Otok, Pivka, and Black Cave

The three caves are connected to the Postojna Cave along the subterranean river Pivka. Each one them is unique and beautiful – they are very much worth a visit, if you have enough time and if you are a true cave fan. The caves can be visited on the adventure tour, but the regular tour is also available for each one of them. A tour of the Pivka and Black Caves takes 1h30, while the tourist section of the Otok Cave takes 45 minutes.

Predjama Castle

The Predjama Castle is located a few kilometers from the Postojna Cave, and it ranks among the ten most fascinating castles in the world. What makes this medieval castle so unique is the fact that it was built in the middle of a 120-meter-high cliff! The castle even holds the Guinness World Record as the world’s largest cave castle.

The Predjama Castle is 800 years old and it hides a network of secret tunnels in the cliff, as well as the cave under the castle. The tour of the castle takes 60 minutes and the audio guide is available in 17 different languages. On the tour, you will be walking through the castle’s armory, chapel, kitchen, torture chamber, and attic. And you will also see a rich collection of medieval weapons and armors!

Cave under Predjama Castle

The cave under Predjama Castle is the second longest Slovenian cave, spreading over four floors, with a total length of 14 kilometers! The tourist section is only 700m long and it can be visited as part of the Castle tour. If you are interested in exploring more of it, you can take up an adventure tour and see all the hidden parts of the cave. But, bear in mind that the cave is closed for visitors during the winter, due to the bats‘ hibernation period.
