In one day, you can easily visit three of Slovenia’s most stunning destinations: the Postojna Cave, Predjama Castle and Škocjan Caves.
Postojna Cave is a 24 kilometers long cave system, made up of four caves interconnected through an underground river. This cave is the longest one in Slovenia and one of the longest in all Europe. As interesting fact, German forces used the cave to store 1,000 barrels of aircraft fuel during World War II.
Predjama Castle is one of Europe’s most dramatic castles. This Renaissance castle, was built in the mouth of a cave halfway up 123-meter cliff around year 1200, but most of what we can see today is from the 16th century.
Škocjan Caves are a unique natural phenomenon included in the UNESCO list in 1986. These caves, one of the largest underground canyons in the world, are truly amazing. They have beautiful stalactites, stalagmites and other rocks formations, but what makes this place so unique is the underground river (Reka River) which disappears into the underground beneath a rock wall.
Postojna Cave and Predjama Castle are near to each other (like 5-10 minutes’ walk), however, from the castle to Škocjan Caves you have around 30 minutes’ drive. To reach them I highly recommend you to rent a car and drive there. It is a one hour drive from Ljubljana and around a 45 minutes drive from the coastal towns.
Some important information
To visit the cave you need to book a tour. The price per adult varies from €25,80 to €27,90, depending on the season of the year you visit the cave.
Before the tour starts, a guide will group you according to the language you chose. Guides speak many languages; Italian, English, German… If you speak different languages I highly recommend you to avoid the English group because it is usually the most crowded one.
Inside the cave
Inside the cave there is a constant temperature of 10 degrees. It is damp and chilly, so I suggest you to wear pants and to bring a jacket to avoid cold. If you get cold easily, you may also want to bring gloves and a hat.
The tour of Postojna Cave starts off with a train ride. The journey is around 4km long and it last less than 15 minutes.
The yellow train drives you through a hall with Murano-glass chandeliers. I couldn’t stop taking pictures since I was amazed at what I was seeing. However, I didn’t know that this was not even the best of what the cave had to offer.
After stepping off the train a guide will lead you through the cave, sharing interesting scientific and historical information. You will follow a well lit path and you will see enormous stalactites and stalagmites, the oldest one – open to the public – is 150,000 years old.
I have read many blogs where people say that taking photographs is not allowed. Well, we could take photos (no flash of course) during the whole tour, so I assume it depends on the guide. Therefore, if you want to take photos of this amazing place, ask your guide before starting the tour.
Less than 10 minutes’ walk from Postojna Cave you will find Predjama Castle.
The entrance fee for adults is €11,90 and the opening hours vary depending on the season of the year. If you plan to visit the castle between May and October, the first tour starts at 9:00 am, otherwise you have to wait until 10:00am to enter the place.
If you are planning to visit both the castle and Postoja Cave you can purchase a joint ticket for €31,90.
Inside the castle
The entrance fee includes an informative audio guide with 29 points of interest throughout the castle detailing its history.
During the visit you will find many original items, as well as replicas in the rooms and halls. Thanks to the audio guide you will learn several interesting facts as you walk among them.
The castle itself is easy to visit, although some areas are very narrow and cobbled, so I recommend you to wear compact trainers.
The audio guide tour lasts around one hour. You can also walk through the castle without the audio guide, in this case inform yourself about its history before visiting it, otherwise you will wander through the rooms without knowing what you are seeing.
Once you finish the visit it can be a good idea to drive 30 minutes to Škocjan Caves
Some important information

Through the underground canyon: The first tour takes places at 10:00am every day of the year. The price per adult varies from €16 to €20 depending on the season of the year you visit the cave.
Following the Reka River underground: This route is only available from April to October. The timetable varies depending on the season of the year but the price per adult remains constant to €12,50. A combined ticket of both tours (1 + 2) costs €24.

In a group of maximum 25 people, you will enter the Škocjan Caves.

Inside the cave there is a constant temperature of 12 degrees, so it is advisable to bring a jacket and hiking boots or compact trainers to avoid cold and to prevent yourself from the slippery floor.
For an hour and a half, a guide will lead you through the caves, sharing interesting historical and scientific information. You will see enormous stalactites and stalagmites, you will walk across a bridge that sits 50 meters over the river, you will see the largest underground canyon in Europe and you will enjoy a unique uphill, downhill walk.
