The best of the Best !
Skip all other tours and do this one. The tour guide Eugene was the best guide ever. The places we visited were extraordinary and the Caves were the MOST SPECTACULAR I HAVE EVER SEEN . Every moment on this tour was a memorable one !!!
Response from the operator: Evgen will be over the moon to read this incredible review! Having a guide who brings such electric energy and passion to every moment turns an already great trip into the absolute highlight of your entire time in Slovenia. And saying the caves are the most spectacular you've ever seen is high praise—but Postojna and Škocjan truly deliver that unmatched, awe-inspiring scale that stays with you forever! What a triumphant note to finish on! Thank you so much for sharing this enthusiastic review and for taking the time to detail your complete journey across Slovenia. It has been a true privilege walking through your retrospective with you—from celebrating top-tier guides like Eugene, Neza, Luka, Barbara, Marina, Sabina, and Vanessa, to providing candid, practical feedback on logistics, walking gear, and weather microclimates. Your insights offer an invaluable picture of the full travel experience. Thank you for choosing to explore Slovenia with us. We wish you safe, incredible, and truly unforgettable adventures wherever in the world your path takes you next!

Magnificent caves and castles.
Great trip. The Predjama castle in the caves, and later the Postojna caves, were magnificent. The size of these cannot be comprehended even once you see them from the inside. Our driver Jan was really good in communicating exactly what we needed to do, and also with all the extra facts during the drive (so drove really smooth). The process of getting tickets for each of these individually (especially the caves) would be a hassle if travelling on your own. So would definitely recommend them in order to get the bureaucracy headache out of the way and have the trip be very smooth.
Response from the operator: Thank you for such a great review! We are so glad to hear you had a magnificent time exploring both Predjama Castle and Postojna Cave—their sheer size and scale really are mind-boggling to experience in person. It is wonderful to know that Jan took such good care of you with his smooth driving, clear instructions, and engaging facts along the way. Your point about skipping the ticketing bureaucracy is spot-on; managing cave entry times and castle tickets independently can quickly turn into a headache, so keeping everything seamless for our guests is always our goal. We truly appreciate your recommendation and hope to welcome you on another tour soon!

Highlights of Slovenia
The caves are amazing. Definitely worth the visit. Lake Bled was fab too. The castle looked better from the outside than inside. Inside was very commercialised but the outside of the castle was great.
Response from the operator: Thank you for taking the time to share your review! We are so glad to hear that you had an amazing time exploring the caves and enjoyed the beauty of Lake Bled. We also really appreciate your honest feedback regarding Bled Castle. The views of the lake from the castle grounds and its striking position on the cliff are truly magnificent, though we understand that the interior exhibits and shops can feel a bit commercialized to some visitors. Your insights are great for helping future travelers set their expectations for the visit. Thank you again for joining us, and we hope to welcome you on another tour soon!

We love kremšnita ( Lake Bled Cake)
My husband and I had a short time In Ljubljana. This tour was a great option to see all 3 sites. Neva was our tour guide for the day. She was so knowledgeable and we really learned so much. Isaac was orienting as a tour guide with Neva as well. He was very helpful and they made a great team for our day. The castle, the cave and Lake Bled are so beautiful. We would certainly recommend them as a guide. Don’t miss out on the opportunity to take this adventure and have one of them as your guide. Make sure you take a Pletna boat ride, walk up the steps and try the cake at Lake Bled.
Response from the operator: Neva and Isaac are going to be absolutely thrilled when they read this! It sounds like you truly got the absolute best out of your short stay in Ljubljana—hitting Predjama Castle, Postojna Cave, and Lake Bled in one go is the ultimate Slovenian triple-header! We love that you got to experience Neva's deep knowledge alongside Isaac's great support, and your checklist for Lake Bled (the *pletna* boat, the church steps, and that world-famous *Blejska kremšnita* cake) is spot-on advice for anyone visiting! Thank you both so much for traveling with us and for leaving such a glowing recommendation. We hope to welcome you back to Slovenia again soon! 🇸🇮✨

The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Postojna cave, Predjama castle and Lake bled from Ljubljana: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Ljubljana.
How much does Postojna cave, Predjama castle and Lake bled from Ljubljana cost?
+
Prices start at $138 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 and Lake bled from Ljubljana take?
+
Plan for about 11.5 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 and Lake bled from Ljubljana worth it?
+
It holds an Outty Ranking of 77 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 45 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 and Lake bled 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, Predjama castle and Lake bled from Ljubljana suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 11.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Postojna cave, Predjama castle and Lake bled from Ljubljana?
+
Around 16 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 11.5-hour experience runs outdoors or after sunset.
Where does Postojna cave, Predjama castle and Lake bled 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.
