Communication was fabulous. They were able to reschedule a pick up location last minute (change of ports with a cruise ship). Ivan, our driver, was so informative and helpful. The van was comfortable and the service spectacular. The Predjama Castle was well worth the visit and the Postojna Caves were mind blowing!!!! We will definitely book with you again if we are lucky enough to get back to Slovenia. Thank you!!
The visit to the caves was the great disappointment of the whole trip to Slovenia: They have no guides who speak Spanish and we made the mistake of taking the tickets (+140 €!!) with the guide in English. They joined us with +80 people with ONE GUIDE for all (watch, of the 90 minutes of the visit, 45 minutes spend waiting and getting on/off the train that travels the 3.5 km out and back, 15 minutes are kept at the end to ensure that you can spend money in the store that they have inside and in between they spend ONLY 30 MINUTES to walk the 1.5 km of cave that they allow in the visit, making ONLY 3 stops of the guide (who had to wait until they all joined) to give explanations, making the whole run, NO information of what we were seeing and NO time to stop to enjoy the visit. It's very sad considering that we scrolled from afar just to see them, and all to sell more tickets.
We are sorry to learn of your unfortunate experience. However, we must respectfully note that you did not participate in a tour organized by our compan., as it is visible from the review that you bought tickets at the cave ( we don't even sell tickets only) In the interest of fairness and accuracy, we kindly ask that such feedback be directed to Postojna Cave directly, rather than placed under our product. However,Postojna Cave is the largest attraction in Slovenia, and during the high season certain days and times naturally attract a higher number of visitors. Furthermore, for guests who prefer languages other than English, the cave provides an audio guide available in 17 languages. This ensures that all visitors receive the full range of information,. But Slovenia is not just a cave, so we are sure you have great memories from your holiday neverthless :)
Beautiful extensive caves viewed on train and on foot. 90 minutes including approx. one km of walking in a cool 10c climate
Great guide, beautiful and immense cave and a very comfortable experience! Our kids really enjoyed it and Koper delivered!
Thank you very much!
What a great tour!! Damien was our guide from Istranka. He was very patient with our group of 35. He's very knowledgeable and did a wonderful job. The caves were AMAZING!!
Thank you so much! Delighted to hear that. We will let Demian know as well!
Train ride through most of the caves. Walking on non slippery surfaces much appreciated. Cave guide was phenomenal!
Happy to hear you had nice time!
This was a wonderful shore excursion! The caves were magnificent! It is a must see if you are in Slovenia. Our tour guide was very informative about the area, culture and history. The pick up point was directly off the ship and they were very punctual in returning us to the ship. Definitely would recommend
Thank you very much! We are happy to hear you had wonderful experience!
So pretty and interesting. Definitely lots of walking and chilly. Couldn’t hear the guide but that was part of the cave staff. Very slippery so wear sneakers. The train was an experience but fun and one of a kind
Thank you very much for your comment!
We had a sensational day. Our guide Sonja, was knowledgeable, Gracious and considerate. She enhanced what was already a great experience. The caves are an absolute must see and th castle is incredible.
Thank you so much for your nice comment!
Very unorganized when I booked tour thought it was for 8:30 in the morning. That was the time tour kiosk opened, tour wasnt until 10:45, was told I was sent a message the day before giving me the time (never received) but how are you going to inform someone the day before of the time? We had other plans later in day which had to be cancel since tour started 2 hrs later then expected. Should inform people of the time when they book not the time you open.
Hello Melissa, We are very sorry to hear you were unhappy and we understand your position. But there is some misunderstanding. We have sent you the message via Viator about the start time on 21st of August, your tour was on 19th of September. So you were not informed the day before, but almost a month before (you can easily check via Viator). It is always important to read the messages that are sent, especially to avoid such issues. All best
