Postojna Cave: Underground Marvels

Reviewers consistently praise the impressive nature of the caves, describing them as “unreal,” “spectacular,” and “breath-taking.” The caves’ massive chambers, delicate stalactites, and underground passages make for a memorable experience.

Next, the tour takes you to Predjama Castle, the world’s largest cave castle perched dramatically high in a cliff. This about-one-hour stop is self-guided, allowing you to explore at your own pace. Many travelers find the setting “romantic” and the history “fascinating,” especially given its 800-year history. From the outside, it’s a striking sight, with its medieval walls jutting from the rocky face.

While you might only have time for exterior views if you choose an outside-only ticket, the guided part of the tour often includes insights from the guide, enriching the experience.
