A perfect half day tour from Ljubljana
We had a wonderful day at the cave and the castle. Our driver was friendly, punctual and offered some insight into what to expect before we arrived at each location. You must do this tour of you go to Ljubljana!
via Tripadvisor
Highly recommend these...
Highly recommend these attractions - both are very interesting although the caves are spectacular and shouldn’t be missed. The team at the cave are highly professional, and provide an engaging and interesting tour. Sadly our driver didn’t match these skills and could have provided a better service but I guess his role was just to get us to where we were going which he did safely and comfortably.

Nice half day excursion.
Efficient. Convenient. Worth the morning. Ferris was lovely and attentive. Small group. Destinations not too far. Caves and castle amazing

Amazing!
Our tour guide was excellent! Very patient and informative! The tour was outstanding! The best to see in this part of Slovenia 🇸🇮 was without any doubt the Postojna cave and the castle! We loved the experience!!!

Top driver, great cave, fascinating castle.
Our driver Faris, was excellent. He was very knowledgeable about cave and castle, he told us exactly what would happen and how the trip works. He was friendly, courteous, thoroughly professional and highly informative. I thoroughly enjoyed the ride to and from Ljubljana and listening to what he said. He spoke just the right amount of the time: not too much not too little. I cannot say the same about the tour leader in the cave. She rushed the group and was hard to understand at times. The cave tour was over crowded - seemed merely a money making venture for the owners, and we tourists were treated like cattle. The cave itself was brilliant, but I wish we'd been allowed more time to linger at certain points to take in the phenomena. The castle was highly interesting, also crowded, but tourists could take as much time as they liked while listening to the really good audio guide.

Postojna cave & Predjama castle half day – all tickets included: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Ljubljana.
How much does Postojna cave & Predjama castle half day – all tickets included cost?
+
Prices start at $121 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 & Predjama castle half day – all tickets included take?
+
Plan for about 5.5 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 & Predjama castle half day – all tickets included worth it?
+
It holds an Outty Ranking of 76 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.6/5 across 120 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 & Predjama castle half day – all tickets included?
+
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 & Predjama castle half day – all tickets included suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 5.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Postojna cave & Predjama castle half day – all tickets included?
+
Around 42 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 5.5-hour experience runs outdoors or after sunset.
Where does Postojna cave & Predjama castle half day – all tickets included 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.
