Very good excursion - Very good excursion with castle and caves. Driver David was very good. Castle done first to avoid crowds. Then to caves where we had 45 min to eat before entering the caves at 11:45. First 20 min by train and then 1.5 hours walking through the caves (no stairs). A very large group with English speaking guide. Make sure you're a little bit ahead. Then again by train 20 min. We were promptly at the agreed time of 14:30 again in Triest for Hotel Savoia Excelsior (opposite cruise terminal).

- Describing the Postunia Caves in Slovenia just a few miles from Gorizia is no easy task. SPECTACULAR!. Lovely place, perfect organization, groups of Italians with native language guide. You enter with a train that crosses narrow corners, then opens the scenery at 10 degrees constant temperature. Stalactites and giant stalagmites that are billions of years old. Over 40 million visitors from all over the world. I won't add anything else so as not to take away the surprise when you visit them. Out of cleanliness, excellent services, very modern places to eat. For Italians espresso coffee is a disappointment.

Amazing Experience - This tour starts by going to Predjama Castle, which is nothing like I’ve ever experienced before. Seeing how this castle was built into the side of a rock face was amazing, and then going from room-to-room to see the inside was interesting. From there, you travel to the Postojna Cave. The caves are 10 degrees Celsius year round, so make sure you have a jacket. I have never been inside a cave system before, so this was a first for me. The rock formations inside were spectacular. FYI, there were no stairs within the caves; it was all ramps. The Castle was nothing but stairs.

We loved Slovenia.... - We loved Slovenia. Beautiful and wonderful places. Would highly recommend David. He was very accommodating providing transport from the cruise ship to the sites in Slovenia. Made sure we knew all about the sights we were seeing, including the castle and the caves! He helped us get our tour tickets set-up, helped us take photos, and kept our luggage safe. He was also knowledgeable about Venice and transportation needs. Parked and walked us to the water taxis area. Helped us with the luggage and to get on a water taxi to our hotel in Venice. Cannot recommend him enough. We had an enjoyable, relaxing day transferring from Trieste to Venice via Slovenia. Definitely a highlight of our two week vacation!!

Caves and Castle - Travelers should know that it is a level activity. They need to be able to do steep stairs and walk long distances.

Not a private tour-Small group - Title led us to believe it was a private tour, it was not. When we returned I read the description again, at the very bottom it says limited to 7, there were 8 on our trip. We were never offered the bottled water. Communication with pick up was good. Guide was personable.
