- Describing the Postunia Caves in Slovenia just a few kilometres DA 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 DA 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!!

Beautiful Day in Slovenia with David - David was very good with communicating with us regarding the planning of the tour and the meeting location. The meet at the port of Koper Slovenia was easy, David was waiting for us. David was very pleasant, informative about sites, his country and directions and spoke very good English which was very helpful to us. David drove us through the lovely countryside to the Postojna Castle for a tour and then to the Postojna Cave. Both were amazing. Just a little warning to those who may be older or dealing with limited mobility (our group was age 67 to 80). If not is good shape, the one hour walk thru the cave can be an entire days work out! First you take a 15 to 20 minute train ride and then walk an hour, some up hill, some downhill, then ride the train for another few minutes. We got a good work out and loved the entire day. David dropped us off in port with plenty of time to spare.
