An Unforgettable Slovenian Adventure with the Best Guide!

We had an absolute blast on this tour! Visiting Postojna Cave, Predjama Castle, and the charming coastal town of Piran was an unforgettable experience. A huge part of what made it so special was our incredible tour guide, Barbara. She is remarkably detail-oriented, genuinely helpful, and went above and beyond to cater to everyone's needs with a smile. We truly couldn't have asked for a better experience and highly recommend this tour package to anyone visiting! And if you are lucky enough to have Barbara as your guide, you are guaranteed an unforgettable journey!❤️

The best part of the tour...

The best part of the tour for me was the cave - it was incredibly impressive! So many different formations; the most I have ever seen. Piran was nice and the views you get from the city walls is lovely even though it was roasting hot. Our guide was absolutely amazing and went above and beyond to ensure that all the bus had a good time.

Good Day Out Seeing The Sights

A good day out with about 45mins which was a little rushed as we had to hurry the last 10 audio hearings. The couple of hours at the caves were great and the 3 hours in Piran was plenty. I wish I did. My research and took swimmers to have a swim in the ocean. Our tour guide was good (unfortunately can’t remember his name) and answered all questions and did a little tour of Piran for about 30 mins.. If this is what you are looking at seeing in a day it is perfect.. It’s about a 11 hour day.. 8am-7pm

Experience that I highly recommend

Magnificent setting, the caves and the castle in the cliff are a must for those who come to visit Slovenia Speedy in the morning and more time to stroll in the afternoon in Piran, very good overall Friendly and patient guide who shared many anecdotes and historical facts with us Thank you!

Great trip 😊

We enjoyed the castle, caves and Piran very much. Our guide George was very knowledgeable and told us lots of facts whilst driving to our destinations. We had just the right amount of time at each place. The castle was interesting, the caves were amazing, the best we've ever seen and it was lovely to spend time in Piran - the Slovenia coastline. It's great to have your own personal mini bus (there were only 6 of us) and have the time to relax and enjoy the trip. I would highly recommend this trip whilst staying in Ljubljana.

Operator response

Djordje is going to be so thrilled to read this! Having a knowledgeable guide who can share fascinating insights along the drive makes the journey just as enjoyable as the destinations. With only six of you in your own private minibus, it really allows for that perfect, relaxed pace to soak everything in without feeling rushed. Predjama Castle, the breathtaking caves, and the sunny seaside charm of Piran make for such an iconic Slovenian trio—and hearing that these were the best caves you've ever seen is the ultimate compliment! Thank you so much for traveling with us, sharing your wonderful experience, and highly recommending the tour to fellow travelers visiting Ljubljana!

Not what we expected.

This was unfortunately not what we expected. It started with our tour guide arriving late because of mechanical issues with the bus. She was disorganized and the tour company mixed two groups together so people were confused about which cave tour we were at since there were two cave groups. Also, instead of being dropped off in Piran, our asked our group if we could walk to Piran together. What we didn’t realize was that this meant we would drive a mile away from old town so she could park the bus. If I had known that we would waste time parking, I would have chosen to be dropped off in town while the guide parked the bus (this is not something customers should spend valuable and money time doing). There was also no time carved into the schedule for lunch and we were starving. We ended up skipping the walking tour of Piran so we could find something to eat. It was a long day but we enjoyed Piran and the caves and castle despite the day and the guide.

Operator response

Thank you for your candid feedback. While we're glad you enjoyed Piran, the caves, and the castle, we're deeply sorry for the frustrating logistics. Bus delays, group mix-ups, the distant parking walk, and a lack of built-in lunch time fall well below our standards. We are addressing these operational issues directly with our team to ensure smoother scheduling and guest convenience moving forward.
