Starting Point and Transportation

We begin the journey in Ljubljana, with convenient pick-up options at three central locations: the InterContinental Ljubljana, City Hotel Ljubljana, and French Revolution Square. This setup makes it easy to join the tour without much fuss. The 6-hour duration includes travel time, so you’re not stuck on a bus all day—just enough time to see some of Slovenia’s top sights.

The vans are comfortable and air-conditioned, which is a relief after walking around in the Slovenian summer or spring. The driver-guide, often highlighted in reviews for their friendliness and knowledge, makes the ride enjoyable and informative. Expect about a one-hour drive to Postojna Cave, then a scenic 20-30 minute ride to Predjama Castle, and a leisurely return.

Postojna Cave: A Natural Wonder

Once inside, the highlights are impossible to miss. The stalagmites and stalactites form spectacular shapes, and the guide explains how these formations develop over thousands of years. The underground train, which many reviewers describe as a fun highlight, whisks you through a large cavern where blind salamanders, or “human fish,” swim in underground lakes—a rare sight that adds a touch of the mysterious to the experience.

The cave tour lasts about two hours, and reviews repeatedly mention how well-organized and informative the guide is. One reviewer said, “The caves are a must, amazing seeing,” emphasizing how captivating the underground world is. Be aware that there’s quite a bit of walking, and surfaces can be slippery, especially if recent rain has made the paths damp. Wearing comfortable, sturdy shoes and bringing a jacket is recommended since the caves are cooler than outside.

Predjama Castle: A Fairytale Fortress

After emerging from the caves, the next stop is Predjama Castle, a true visual spectacle. Perched against a dramatic cliff and built into a natural cave, the castle looks as if it’s straight out of a storybook. The Renaissance architecture and strategic location make it a fascinating visit. A guided tour with an audio guide allows you to explore the castle’s nooks and crannies, giving insight into its history and legends.

Recent reviews highlight the impressive architecture and the scenic views of lush Slovenian countryside from the castle grounds. The approximately hour-long visit is enough to soak in the atmosphere and take plenty of photos. Some reviewers wish they had more time here—”about 50 minutes felt a bit rushed,” one said—so if you’re a castle enthusiast, you might consider this when booking.
