Wonderful tour, guide and driver - We took the Postojna Cave and Predjama Castle today with guide Earnest and driver Eddie. Fabulous experience. Thank you. (Note: lots of stairs at the Castle, be forewarned.)

Amazing a definity must. - I would say if you only had one thing to see in Koper, then go see Postojna cave. It'll be nothing that you have ever seen before. Simply Amazing.

A pleasant day and a pleasant guide! - What an unexpected gem our visit to Slovenia was! We loved the visits to the cave and castle. We had a private tour with Mateja as our guide. She was just wonderful! She was pleasant, friendly, informative, and put up with our crazy group of 13 with grace. Our brief visit showed us what a beautiful country Slovenia is and we will definitely be back one day.

Fantastic tour guide made the trip worth it - The meeting spot for the tour is centrally located and the bus was comfortable. The two sites are a perfect short day trip from Trieste. Our guide, Ernie, was good humored, informative, and helpful. His mixture of serious information and “fun facts” was perfect. He told us a few good jokes as well on the drive back to Trieste. The bus driver was an expert and we all felt safe. We would definitely recommend taking this excursion with KoperTours.

Something was wrong with timing. - This was a very exciting excursion. The caves were absolutely magnificent. The set up that they have for people to be able to see this marvel is excellent. I would highly recommend seeing these caves for anybody in that area of the world. My only complaint would be that when we went to the castle (which was also so beautiful and magnificent ) the tour guide said we were running late and we only had 10 minutes to run and take a picture and run back. It was very stressful. I didn’t like that. And then we actually got back to our return spot an hour earlier than we were supposed to, so I felt that there was something that got mixed up there and it made it so we didn’t have as good as time as we could have.
