The tour begins with a pickup from your accommodation or cruise terminal in Rijeka. This is a big plus, especially if you’re trying to avoid the hassle of coordinating transport or dealing with crowded public transit. According to a reviewer, the process was smooth, with friendly multilingual staff guiding guests to the ticketing area, avoiding queues, and making everything straightforward.

Once at Postojna Cave, you’ll step into what is often called “the queen of all caves.” As one of the most famous caves in the world—and Slovenia’s top tourist attraction—it’s renowned for its vast underground tunnels, stalactites, stalagmites, and impressive formations. The admission fee is included, so you won’t have to worry about extra costs, and you’ll have approximately two hours to walk through the cavern.
Expect a guided train ride through parts of the cave, which makes navigating the extensive tunnels manageable and fun. The temperature inside remains a constant 10°C, so bring warm clothing—something a reviewer mentioned as a practical tip.

The admission fee is included here, too.
Spending around two hours here allows you to wander the castle’s rooms, walk along battlements, and soak in the views of the surrounding countryside. The castle’s commanding position offers fantastic photo opportunities and a sense of stepping back in time. The story of Erazem, combined with the castle’s impressive architecture and cliff-side location, really captures the imagination.
A review mentions how the castle “reigns over the surrounding area,” giving visitors a sense of its strategic importance. The guide’s storytelling here makes the history come alive, especially when recounting the daring exploits of the legendary robber.
