The Postojna Cave is a highlight on this tour, with a 1.5-hour visit inside this 24,340-meter-long karst cave system. Known as one of Slovenia’s premier tourist sites, it features a fascinating underground world shaped by water droplets over millions of years.
The journey into the cave includes a ride aboard an underground train, which transports visitors through stunning stalactites, stalagmites, and other mineral formations. While entrance tickets are not included, the visit offers an unforgettable experience of walking through a subterranean landscape filled with natural wonders. The caves are known for their expansive chambers and intricate formations, making this stop a must for lovers of natural beauty.
Following the cave, the tour reaches Predjama Castle, a dramatic Renaissance fortress built halfway up a 123-meter-high cliff into a massive cavern. The 1.5-hour visit allows time to stroll around the castle’s exterior and take photos of this extraordinary structure.
This castle is famed for its unconquerable appearance and history as a defensive stronghold. Its unique location and medieval architecture make it a favorite among visitors seeking striking views and photo opportunities. Like the cave, entrance tickets are not included, but the castle’s commanding position and dramatic setting make it well worth the visit.

One of the tour’s key advantages is the private, air-conditioned vehicle that transports your group between sites, ensuring a comfortable ride no matter the weather. The bottled water provided on board keeps you hydrated throughout the day, and the pickup service from Zagreb streamlines the journey.
This setup reduces the hassle of coordinating multiple transport options, allowing you to focus on enjoying each stop. The private nature of the tour also means it can be tailored slightly to your group’s interests or pace, offering a more personalized experience.

The itinerary balances sightseeing with manageable time allocations at each stop. The Ljubljana Old Town is a guided walk, while the cave and castle visits involve walking and some staircases, requiring moderate physical fitness. The tour’s pacing ensures you see the highlights without feeling rushed, but travelers should be prepared for some walking and uneven surfaces.
The duration ranges from 8 to 12 hours, depending on traffic and how long you choose to spend at each site. Starting early is advisable to maximize time, especially if you wish to explore more on your own after the guided portions.

While the tour price covers transportation and a guided orientation of Ljubljana, the admission tickets for Postojna Cave and Predjama Castle are an additional €50 per person. This fee grants access to the underground train in the cave and the castle interior.
Booking confirmation is immediate, and the experience is non-refundable. The tour operates only for your group, providing a bespoke experience, but it’s important to note that refunds or changes are not possible after booking.
