Postojna Cave & Predjama Castle from Trieste

GaryJohn_L, May 2026

Really great tour!

We had a great tour thanks to Stephan. The sights were amazing and he also took good care of us. A small group and lots of information but friendly, polite and not rushed. He is a proud Slovenian and enjoyed showing off his beautiful country. We especially enjoyed the castle and the ride there.

Cave and castle tour

It was very nice to have a pick up at certain hotel when booking this tour; however, on the day of the booking it was a bit unorganized. There were many different tours at the same time and I had to ask several guides to see which tour I belonged to. We almost missed out tour if our guide didn't scream out loud the type of tour and his many people he's missing. Beside the unorganized picking up the group, the tour was very thorough. The drive was good.

Private Postojna Cave & Predjama Castle Tour from Slovenian Coast

Brian_P, Apr 2026

Rushed but very worth while !

Even though Mateo was a great guy and driver-it would have been nice to have a real tour guide w us explaining all of the sites on our dive to and from the cave and castle. We had to cut our tour short due to Viking changing their time of departure last minute! Which they heard about in their review ! So we were rushed most of the time. But Mateo was great insuring we were back to the boat on time for their ‘early’ departure! Also nice just having our group of 8 on this excursion!

Excellent tour

We had an excellent experience on this tour. The driver and guide arrived on time and completed everything as scheduled. Although I don’t recall the guide’s name, he had very good knowledge about Slovenia and explained everything clearly. The entire tour was well-organized with no rush at any point. Fellow tourists were very friendly, which made the experience even more enjoyable. All the tourist sites we visited were wonderful. I highly recommend this tour 100%.
