Postojna Is a hike but SO worth it

Postojna Is remarkable. Well worth the trip and price of admission. The Castle is fine, but you don’t really have much time to explore there. Tour guide and transport was excellent. Pro tip: bring a sweater cause it gets chilly in that cave.

Great tour

Due to unforeseen circumstances, they switched my full day tour to half day afternoon tour (only the cave and castle but with tickets covered). Things still worked out. Appreciated Matt the tour guide's enthusiasm and knowledge, also the little thoughtful surprise at the end of our cave tour. The cave is a must-see!

The Postojna Cave & Predjama Castle - Small Group Tour from Trieste

The Postojna Cave & Predjama Castle - Small Group Tour from Trieste was even better than we imagined! The Predjama Castle was absolutely incredible—built right against the wall, it’s a sight to behold. There were lots of stairs to climb, but we loved the architecture. The Postojna Cave was truly spectacular. Stephan, our driver, was so friendly and shared his knowledge of the region with our group.
