11.Postojna Cave and Castle Small-Group Day trip from Ljubljana

★★★★★★★★★★4.5 · 101 reviews · 5 hours 30 minutes (approx.) · from $128

Travel from Ljubljana in a small, air-conditioned vehicle to Predjama Castle and Postojna Cave. You’ll see a castle built into a cave mouth, ride an underground train, and walk through cool limestone chambers. Guides such as Miha, Matej, Luka, and Ksenija have been praised for adding local history, though some departures feel rushed.

“A nice trip. The pickup was quick and efficient. You get audio guides at both attractions, which takes away from the experience. I wish the guide use the transport/waiting time to explain and talk about the attractions to offset the audio guides a bit. Instead we got really uncomfortable discussions on abortion politics, not really what I'm looking for on a vacation, sorry. I'm very happy I was able to join the tour last minute due to changes in another tour. The operator was very easy to communicate with.”
