About This Tour

This Postojna Cave and Predjama Castle half-day trip takes you from Ljubljana to two of Slovenia’s best-known sights in about five and a half hours. Entrance tickets for both places are included, and the group is capped at 8 people. It suits travelers who want to see the cave and the castle without driving, buying tickets or planning the route themselves.

The stops

  • Postojna Cave (about 1.5 hours): you ride an electric train deep into the cave, then walk through chambers full of stalactites, pillars and thin limestone curtains. It’s one of the most visited karst caves in the world, and the size of it is what most people remember.
  • Predjama Castle (about 1 hour): an 800-year-old castle built into the mouth of a cave, halfway up a cliff. It’s the largest cave castle in the world. Inside you see the armory and furnished rooms, and you hear the story of Erasmus, a local knight often called the Slovenian Robin Hood.

The order of the two stops can change on the day. Between them, the drive takes you through the green Karst countryside.

What past travelers say

Past travelers like the small group, the punctual pickup and drop-off, and the fact that the stops are not too far from Ljubljana. Several also say the walk inside the cave is long, with a fair number of slopes, which is worth knowing for older travelers.

It was wonderful with a...

It was wonderful with a great tour guide. Had an amazing experience the cave itself is very beautiful amazed how big it was. Definitely worth visiting.

Wonderful lessons from a well-informed guide

Beautiful sites, small group, terrific guide! The countryside is beautiful, rich history lessons. The castle and caves were a great experience. One thing, for you older travelers, the walk in the caves is quite long with a lot of hills.

Frequently Asked Questions

Is this a fully guided tour or mostly transport and tickets?

Your driver-guide takes you to both sites and shares background on the way. Inside Postojna Cave, the cave’s own guides lead the tour. At Predjama Castle you visit with an audio guide. Some past travelers wanted more commentary from the driver, so expect the depth of the visit to come mostly from the sites themselves.

How cold is it inside Postojna Cave?

The cave stays at around 10°C all year, even in summer. Bring a light jacket or sweater.

How much walking is there?

  • Postojna Cave: a long walk after the train ride, with slopes up and down. The paths are paved but can be damp.
  • Predjama Castle: stairs and narrow passages between rooms.

Most people manage fine, but it can be tiring for travelers with limited mobility.

Who is this tour not a good fit for?

  • Wheelchair users, as the tour is not wheelchair accessible.
  • Travelers who find long walks with slopes hard.
  • Anyone who wants to add Lake Bled or the coast on the same day. This is a half-day trip with two stops.

Is it worth booking a tour instead of driving myself?

If you don’t have a car, yes. The tour covers transport and both entrance tickets, and you don’t need to plan the timing between the cave and the castle. Travelers with a car and a flexible schedule can also do it on their own.

What is the cancellation policy?

You can cancel for free up to 24 hours before the tour starts (local time). If too few people book, the tour may be cancelled, and you get an alternative or a full refund.

Can I bring young children?

Yes. Infant seats are available in the vehicle. Keep in mind the walk in the cave is long for small kids, and it is cool inside, so bring an extra layer for them.
