Gems cut out of the rock One cannot visit Slovenia without visiting Postojna Cave, the largest Karst cave in Slovenia with as much as 24 km of fantastic grid of tunnels, galleries and halls.

Visit impregnable Predjama Castle that reigns perched high up a vertical cliff.

    2. Postojna Cave

      The Pivka river has been carving the Postojna Cave for 2 million years. The water level has changed over time and created a beautiful "multi-level" underground world filled with stalactites, stalagmites, columns, curtains and other gorgeous shapes was gradually created as the water was leaving layers of limestone behind. The first visitors supposedly came to the cave as early as the 13th century, but the most beautiful parts of the cave were discovered in 1818. You’ll enter the cave by train. The train ride takes about 10 minutes, and then you’ll continue on foot with a guided tour. Stroll under the needle-thin transparent tubes hanging from the ceiling in Hall of Tubes. From under the Russian Bridge you will reach The Concert Hall from where you can see the amazing white Brilliant – a truly breathtaking sight. Despite dark, around 100 animal species live in the cave! The main attraction is, of course, the proteus, which was at first mistaken for a baby dragon.

    3. Predjama Castle

      Before visit, take a break on the terrace of the country inn in front of the defiant, mysterious Predjama Castle built in a rock and enjoy its stunning views. The castle is built as an impregnable redoubt, placed in the gaping mouth of a cavern halfway up a 123 m cliff. The castle holds great features – holes in the ceiling of the entrance tower for pouring boiling oil on intruders, deep and dank dungeons, and an eerie hiding place at the top called Erazem's Nook. After a nice half day experience we will return back to Ljubljana. Drop off will be at same location as pick up.

    1.5 km of jogging

    this "tour" was not exactly what we thought it was. The word tour indicates that there will be an interaction with the guide. He gave a few instructions, and then we were off. After the train ride, we got off and started walking. It was not a stroll, he was a extremely FAST walker, and did not stop once for any picture taking, which was disappointing. We are glad that we took the tour, but would have liked to take some pictures. Take the Vintner Gourge experience, it is amazing.

    Exciting tour to Postonja cave and Predjama castle!

    Great half day trip to one if the oldest cave near Ljubljana. Shirt ten minutes rides to Predjama castle was great too. Our guide Milan was great and explained lot of history about the town Ljubljana. Only thing is he drove us to both the locations and after that we were on our own. If you stay in Ljubljana I don’t think it’s worth paying someone to drive you to caves and castle. You can easily hired a taxi I guess to visit the place. This is my opinion, everyone has different comfort level when they travel. Highly recommend seeing Borge the places.

    A Great Half-Day Tour

    An excellently organised and delivered tour. We were met at 08:30 around the corner from our hotel (a hotel pick-up would have been available had we not been staying within a pedestrianised zone) where our courteous guide gave us information on the caves, castle and the history of Slovenia and its people on the way to our destinations. Although on booking there was a warning that the tour may be cancelled if there were insufficient numbers, there were only three of us in our party and no one else joined us so it turned out we had our own private transfer service which was great. Our guide explained that he would be able to do the trip in any order but due to the weather conditions advised to stick to the caves first as there was a chance of rain first thing which would pass by the time we got to the castle. We heeded his advice which definitely paid off as we avoided the rain whilst we went inside the caves and arrived to the castle in glorious sunshine. It was good touch that he was able to offer this flexibility on his own back to give us the best possible experience. Tickets were bought on our behalf by our guide who showed us the way towards the cave entrance. Here we joined several other tour groups and queued for the appropriate language. Whilst there was a considerable number of people for various languages, due to the staggered approach of getting people underground it did not feel crowded. After the train journey in, the tour was given at a good pace and allowed time to take in the caverns with about a 1-1.5 hour walk. The castle was also very impressive. Those expecting a lot of decorative items, furniture and the like should be aware that these are kind of sparse throughout, although there is a decent little armoury where you can have a go and lifting the unwieldy sized longswords. The main attraction comes from how the castle is set into the cave face and how features of the cave became both its strength and weakness. An audio guide is available and I found this to be very informative of its history. After our self-guided tour of the castle we met our guide once more in the car park where we were returned to the pick-up point around 13:50 after a very enjoyable half-day. A highly recommended tour.

    Postojna Cave is really a wonder of nature!

    The cave is an amazing wonder of nature. I thought this is just similar to the cave in Halong Bay of Vietnam but this is bigger and indeed the mother of all caves!The Prejama castle is also interesting. Don't expect treasures nor a lot of furnitures but what's interesting is the location of the castle and how it was built as part of the cave system. A must-see site in Slovenia

    Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Ljubljana.

    How much does Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana cost?

    +

    Prices start at $147 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Ljubljana usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana take?

    +

    Plan for about 5 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Ljubljana is not rushed.

    Is Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana worth it?

    +

    It holds an Outty Ranking of 62 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.6/5 across 5 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Ljubljana, and how flexible the cancellation terms are.

    Can I cancel or reschedule Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 5-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana?

    +

    Around 2 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Ljubljana can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Ljubljana and add a light layer if any part of the 5-hour experience runs outdoors or after sunset.

    Where does Postojna Cave with Train Ride and Predjama Castle Half Day Trip from Ljubljana start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Ljubljana within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Ljubljana?

    +

    On Outty we rank every Ljubljana experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Slovenia in One Day: Small-Group Bled, Postojna Cave & Predjama, Postojna Cave and Predjama Castle - Entrance Tickets Included, Ljubljana Small Group Food Walking Tour. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Ljubljana?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Ljubljana?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
