Postojna Cave
Postojna Cave, the queen of all caves, is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you get to meet this underground kingdom’s most famous inhabitant – the proteus (olm) – up close. A fantastic web of tunnels, passages, galleries and halls, astonishing diversity of karst features, as well as easy access are certainly the main reasons for such popularity of the cave and a large number of visitors (more than 36 million of them in over 200 years).

Predjama Castle
The Predjama Castle reigns over the surrounding area, not far from the Postojna Cave, in the idyllic village of Predjama. This picturesque, magnificent, defiant, mysterious and impregnable castle has been perched up in the middle of a vertical 123-meter high cliff for more than 800 years. Its romantic appeal is further emphasized by the idyllic Lokva River, which disappears into the underground world deep down below the castle. As the only preserved cave castle in Europe, the Predjama Castle offers a unique insight into the building techniques and resourcefulness of people in the Middle Ages, who were looking for and found a safe harbor for themselves right at the entrance into the cave. During a siege that took place in the 15th century, the castle provided a refuge for its best known and most notorious owner - Erazem of Predjama. The legend about the courageous robber baron Erazem, who remained undefeated until one of his servants betrayed him, is still in people’s minds, inspiring and alluring as ever. It was this safe abode of his which helped the brave knight resist the besiegers without much difficulty for more than a year.

Great tour!
Great tour! Our guide Ernie was great. I wish we had had more time in the castle—it was a fascinating place! I definitely recommend this tour. Only tip would be to get food whenever you can—there’s no time for a sit down lunch.
via Viator
Cave and electric train
Ernest was a great guide, full of energy and sense of humor and information. Wish the description of the tour had mentioned the cold temperatures while touring in the train. Also, the description could include options to just tour by train and no walking. Reminded me of Krakow salt mines.
via Tripadvisor
Easy visits to sites plus local knowledge that made for a better experience
Having a knowledgeable local take us to the castle and cave made for a more relaxing experience. So easy with the pick up at the house where we were staying. Dejan shared about Slovene culture and history and educated us on local restaurant styles. We most enjoyed the cave tour—fascinating.

Why this scores 66
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Postojna Cave & Predjama Castle - Shore Excursion from Rijeka: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rovinj.
How much does Postojna Cave & Predjama Castle - Shore Excursion from Rijeka cost?
+
Prices start at $129 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Rovinj 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 - Shore Excursion from Rijeka take?
+
Plan for about 7 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 Rovinj is not rushed.
Is Postojna Cave & Predjama Castle - Shore Excursion from Rijeka worth it?
+
It holds an Outty Ranking of 66 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.7/5 across 10 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Rovinj, and how flexible the cancellation terms are.
Can I cancel or reschedule Postojna Cave & Predjama Castle - Shore Excursion from Rijeka?
+
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 - Shore Excursion from Rijeka suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 7-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Postojna Cave & Predjama Castle - Shore Excursion from Rijeka?
+
Around 4 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 Rovinj 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 Rovinj and add a light layer if any part of the 7-hour experience runs outdoors or after sunset.
Where does Postojna Cave & Predjama Castle - Shore Excursion from Rijeka 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 Rovinj 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 Rovinj?
+
On Outty we rank every Rovinj experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include BUBA-Kayak Tours Rovinj FREE-drinks,pictures,snorkeling equipment, Rovinj amazing kayak tour-free drink &snorkeling &jumps &photos, Truffle hunting adventure. 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 Rovinj?
+
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 Rovinj?
+
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.
