This Postojna Cave, Predjama Castle and Piran tour from Ljubljana covers three very different parts of Slovenia in one day: a huge cave system, a castle built into a cliff, and an old town on the Adriatic. It suits first-time visitors who want to see both the karst and the coast without driving themselves.
The visit starts with a train ride into the cave, then a guided walk past stalactites, stalagmites and large halls carved by the Pivka River. Look out for the olm, a blind salamander that spends its whole life in darkness. You have about two hours here.
Next is Predjama Castle, a Renaissance castle set into a 123-meter cliff, with caves running underneath it. It’s in the Guinness Book of World Records as the largest cave castle in the world. Inside is a museum with objects found on site, like goblets, cups and candlesticks. Plan about an hour and a half.
The day ends on the coast in Piran. The old town has narrow streets, closely packed houses and a town wall you can climb for views over the sea. You’ll see Tartini Square, with the statue of composer Giuseppe Tartini, who was born here, and St. George’s Parish Church. There are about two hours to walk around or just sit by the water.

Our guide DJ lead us on quite an adventure to the three locations. He was most professional and fun to be around. Pick up and safety issues were great and the whole day was perfect. It would take days to describe and comment on the sites visited, but rest assured they should not be missed. Thanks again DJ for your efforts. Mike Talluto
Excellent. The pre-tour communication was good and the driver-cum-tour guide was knowledgeable, personable and helpful. The sights were worth the few hours driving, particularly the spectacular caves.
So glad to see that Nate was our tour quide again. It is a long tour but Nate gave us great information and directions. Recommend this tour! Nate knowledge and sense of humor made the whole day a special trip!
No. Entrance fees for the cave and the castle are paid separately. If you only want to see the cave, there’s a cave-only ticket option without the castle.
It’s a long day of about 10 hours, with a fair amount of time in the minivan between stops. You also walk in the cave and on stairs at the castle. It’s not wheelchair accessible. If that sounds like too much, a half-day trip to just the cave and castle is an easier option.
Yes. Past travelers say guides sometimes switch the order because of weather or traffic, for example to visit Piran when it’s sunnier. All three stops stay in the day.
