    Great caves and castle

    The caves are amazing. There is a train ride into the caves then a good walk through the caves with a guide. The guided tour in the caves is not very good as there are up to 100 people with one guide and it is very hard to impossible to hear what the guided tour has to say. Worth the experience tbough. The castle is quite unique. Not enough time in Ljubljana as we were caught in a traffic jam for a while

    Response from the operator: Many thanks for joining the tour and taking time to post this review. We always appreciate feedback from our customers and wish you an enjoyable stay in Croatia!

    Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb: questions travelers ask

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

    How much does Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb cost?

    +

    Prices start at $217 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Zagreb usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb take?

    +

    Plan for about 11 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 Zagreb is not rushed.

    Is Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb worth it?

    +

    It holds an Outty Ranking of 77 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 35 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Zagreb, and how flexible the cancellation terms are.

    Can I cancel or reschedule Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb?

    +

    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 Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 11-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb?

    +

    Around 12 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 Zagreb 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 Zagreb and add a light layer if any part of the 11-hour experience runs outdoors or after sunset.

    Where does Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb 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 Zagreb 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 Zagreb?

    +

    On Outty we rank every Zagreb experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Zagreb Highlights: Old Town, WWII tunnels, Funicular & Tastings, Communism & Croatian Homeland War Tour, Zagreb: Plitvice Lakes & Rastoke Guided Day Trip with Ticket. 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 Zagreb?

    +

    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 Zagreb?

    +

    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.

    What is included in Ljubljana, Postojna Cave&Predjama Castle with Tickets from Zagreb?
