About this guide

PostojnaCavePredjama.com is an independent visitor guide to Postojna Cave, Predjama Castle and the tours that reach them from Ljubljana and nearby cities. We are not Postojna Cave Park, which runs both sights, and we are not a tour operator or Viator. The site name describes the places we write about, not a business. We compare the bookable tours so you can see which ones include the entrance tickets and which do not.

Facts on this site are checked against the official Postojna Cave Park website (prices, timetables, rules), the live Viator listings (prices, inclusions, meeting points and recent guest reviews) and the official Škocjan Caves Park website for the comparison guide. Prices and schedules move; when a listing and this page disagree, the checkout price wins.

The site is funded by affiliate commissions: when you book through a Viator link here, we may earn a commission at no extra cost to you. That never changes what we recommend, including pointing out which tours leave the tickets out and repeating the complaints guests make. Details on the affiliate disclosure page.
