About this guide
Postojna Caves Guide is an independent travel guide. We are not the official website of Postojna Cave, Predjama Castle, Postojna Cave Park, any tour operator or tourist board.
For official tickets, tour timetables and opening hours, go to Postojna Cave Park (postojnska-jama.eu).
What we do
We write practical pages about visiting Postojna Cave and Predjama Castle: what the visit is like, which ticket suits you, and how to get there. Where a tour makes the logistics easier, we link to tours you can book.
Practical details were last checked in September 2026. The park changes timetables and prices, so its website is always the final word.
How we choose tours
The "Check price & dates" buttons link straight to tour listings on GetYourGuide. We aren't paid for those links, and we have no commercial relationship with GetYourGuide, any tour operator or Postojna Cave Park. If that ever changes, we'll say so here and next to the links.
We list tours because they fit the page they're on: a clear starting point, what's included and the time it takes. The descriptions on this site are our own. For exact inclusions, times and prices, always read the listing itself. If you only want cave tickets, buy them on the official website.
