Excellent Day!
EXCELLENT GUIDE! Nenen was fantastic! Although it was a rainy day, he came prepared with umbrellas, a wealth of knowledge and he drove very safely on the highways. We enjoyed spending the day with him as he was professional, fun, and incredibly bright. He answered all of our history and site questions with a keen sense of intelligence and insight. He also took us to two fantastic spots for lunch and desert. We highly recommend Nenen as a tour guide and we wish him continued success!
Response from the operator: Dear Karyn, I’m really happy to hear that You’ve enjoyed our private day-trip to Slovenia with Neven as Your guide. Also, big thanks for taking Your time to wrote a wonderful feedback here on TripAdvisor. All the best! Aleksandar

Why this scores 46
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Zagreb.
How much does Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb cost?
+
Prices start at $474 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 Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb take?
+
Plan for about 8 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 Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb worth it?
+
It holds an Outty Ranking of 46 out of 100, which we label "Worth a Look". That score blends traveler sentiment (5/5 across 1 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable culture & history in Zagreb, and how flexible the cancellation terms are.
Can I cancel or reschedule Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb?
+
No. This experience is sold on a non-refundable basis, so only book a date you are confident about. Similar experiences in the city do offer free cancellation if flexibility matters more than price.
Is Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 8-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Private tour to Ljubljana, Postojna Cave & Predjama castle from Zagreb?
+
Around 0 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 8-hour experience runs outdoors or after sunset.
Where does Private tour to Ljubljana, Postojna Cave & Predjama castle 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 Communism & Croatian Homeland War Tour, Zagreb Highlights: Old Town, WWII tunnels, Funicular & Tastings, Old Zagreb Private 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 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.
