    Fantastic trip from Doman!

    A fantastic and memorable experience, Doman was our tour guide, he was kind, polite, friendly and knowledgeable. A true asset to their team! The castle trip was brilliant and Doman showed us round, answering questions with exceptional enthusiasm. We then went to the cave, which was mesmerising, before taking us back to Ljubljana, providing further information about this beautiful country. Joe & Phoebe

    Excellent tour- good value

    Our guide was very knowledgeable and friendly. Only four of us on the tour. Comfortable air conditioned mini van. The caves were spectacular, as was the castle. Definitely recommend ( remember to bring a warm jacket as it’s very cold in the caves)

    Efficient visit to Postojna caves and castle

    My husband and I took the half-day tour to the Postojna Caves and Castle. My main criticism of the tour is the deceptive advertising. The price on the brochure is listed in large letters as 68 euros. While en route to the cave, I was taken aback when our driver asked if we had paid the entrance fee yet. I thought we had, but when I looked again at the brochure I had brought with me, I saw that I had failed to read the fine print - the entrance to the caves and caste is an additional 35 euros. Fortunately, we were able to pay for the entrance fees over the phone with the Roundabout Travel office, which tells me that we were not the first people who failed to read the fine print. I could understand if you are selling a tour to a site (such as Bled) where there are things to do (admire the scenery, take a stroll or have a snack) that don't necessarily involve taking in an attraction, then by all means advertise the cost of the transportation. On the other hand, if you are advertising a tour that has no other purpose than to see the site you're going to (such as the Postojna caves and castle), then include the entrance fee in your total - unless you think that total is too high and will turn people away. Better to lure them with the 68 euros and then sock them with the additional 35 when they have no other option but to pay it. Cost aside, the van arrived on time and our driver was pleasant and efficient at directing us to where we needed to be once we arrived at the caves. We arrived about a half hour ahead of the 10:00 tour so there was a little time to shop if desired or use the restroom. After the caves we had a short drive to the castle. We had a little less than an hour to spend at the castle and could have used maybe an hour and half, but I understand that given the time constraints of the half-day tour, this is about all the time that could be allowed. As it was, we hit traffic on the highway back to Ljubljana and arrived about a half hour later than 2:00 time that was advertised, but that was not the driver's fault, and the time was not an issue for us. In summary, if you have no other way to get to the caves and castle, this is an efficient way to do it and you will get to see enough to make the visit worthwhile. The Postojna caves are a marvel, and the castle is quite interesting. Just be sure to read the fine print.

    Highly recommended when in Ljubljana.

    Communication was excellent right from the beginning. Igor was our guide and did a wonderful job taking care of us. His narration in the castle was outstanding and he was simply a very nice person to spend the day with. His driving was outstanding too which was greatly appreciated with the rainy day. The caves are excellent and Igor escorted us to the line at the entrance and then was waiting for us at the end. His attention to detail was greatly appreciated.

    Postojna cave & castle | Private 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 & castle | Private half day trip from Ljubljana cost?

    +

    Prices start at $719 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 & castle | Private half day trip from Ljubljana 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 & castle | Private half day trip from Ljubljana worth it?

    +

    It holds an Outty Ranking of 53 out of 100, which we label "Worth a Look". That score blends traveler sentiment (4.7/5 across 6 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 & castle | Private 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 & castle | Private half day trip from Ljubljana 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 & castle | Private 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 5.5-hour experience runs outdoors or after sunset.

    Where does Postojna cave & castle | Private 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.
