About This Tour

This Postojna Cave and Predjama Castle small group tour takes you from Ljubljana to two of Slovenia’s best-known sights in about five and a half hours. It suits travelers who want both places in one half day, with a guide and no more than eight people in the van.

Predjama Castle

The first stop is a castle built into the mouth of a cave, halfway up a cliff. You spend about an hour inside, climbing narrow staircases and walking through rooms with old furniture and weapons. Your guide tells the legends tied to the castle along the way.

Postojna Cave

Next comes Postojna Cave, where an electric train takes you deep into the cave system. Then you continue on foot past stalactites and stalagmites formed by the Pivka river over a very long time. You also learn about the animals that live underground, including the blind salamander that locals call the “human fish”. Plan for about an hour and a half here.

What past travelers say

  • Past travelers mention that the guides share a lot of local history and don’t rush the group, so there is time for photos.
  • Some note that the cave walk is longer than expected and that the main stops inside can get crowded.

Practical info

  • Duration: about 5 hours 30 minutes.
  • Meeting point: Dalmatinova ulica 10 in Ljubljana, opposite City Hotel. The tour ends at the same spot.
  • Entrance tickets for the castle and the cave are not included, so you pay them on top of the tour.
  • The cave stays at 9°C (48°F) all year, so bring a warm layer and good shoes.
  • The castle has a lot of stairs. A moderate fitness level is needed, and the tour is not wheelchair accessible.

Reviews and rating from Viator & Tripadvisor

Rated 4.8 out of 5 (174 reviews)

A great trip visiting two must see places.

A great trip combining two excellent places. Mini bus very comfortable and plenty of space. Brilliant communication and clear instructions from Viator from booking til the morning of the trip. Easy to find meeting point. Caves were incredible and the castle very interesting. Well worth visiting.

Postjama Caves & Castle

Caves were amazing, highly recommend. Our tour guide was excellent. We had sick kids and luckily ended in private family tour only. He was accommodating and knowledgeable. Went to castle for a quick visit. Amazing

The walk in the cave is...

The walk in the cave is not for the faint of heart several km and a large crowd of people at each stop, but was very pretty and would still recommend! The train into the cave was like a Disney ride but slower. Would recommend bringing a snack as the tour day is packed tight.

Frequently Asked Questions

Are the entrance tickets to Postojna Cave and Predjama Castle included?

No. The tour covers transport and the guide. You pay the entrance tickets for both places on top of the tour price.

What should I wear for this tour?

  • A warm jacket or fleece, even in summer. The cave is 9°C (48°F) all year.
  • Comfortable shoes with good grip. Cave paths can be damp and the castle has steep stairs.

Is the cave crowded?

It can be. Postojna is one of the most visited sights in Slovenia, so you share the cave with other groups, mostly in summer. Spring, autumn and winter are usually calmer.

Who is this tour not a good fit for?

  • Travelers who use a wheelchair, as neither site is accessible on this tour.
  • People who struggle with many stairs or longer walks.
  • Anyone who wants Lake Bled on the same day. This tour covers only the cave and the castle.

Should I bring food?

A snack and a bottle of water are a good idea. The day is full, and one past traveler suggests packing something to eat between stops.

What happens if not enough people book?

The tour needs a minimum number of travelers. If it is canceled for that reason, you get a different date or experience, or a full refund.

Can I cancel my booking?

Yes. You get a full refund if you cancel at least 24 hours before the start time. Later cancellations and changes are not refunded or accepted.
