Very relaxed day without much planning required - The tour operator was at the expected location on time. He gave us much information on the way to Postojna. We were able to walk around a little before the cave tour started. The cave tour was great! I loved the little train ride and the information we got during the walking part. Predjema castle was gorgeous. It was nice to walk around the castle at my own pace. There were many rooms to see.

Incredible tour - The tour was amazing. The cave is breathtaking, one of the most incredible landscapes I've ever seen in my life. The castle is also fabulous, a truly unique structure. Both are must-sees in Slovenia. Our guide, Miguel, was incredible—very competent, friendly, and attentive. Everything went perfectly. I highly recommend this tour to everyone!

Fabulous guide. Excellent trip. I highly recommend - Postojna Caves are a must-see when visiting Slovenia. They are spectacular. The combination of the 6km train ride and the 1km walking was perfect. And Predjama Castle is very interesting being built onto the side of the mountain and connected with the cave system. It's unlike any other castle!

Great Tour with a Great Tour Guide!!! - We really enjoyed this tour, and I would highly recommend the To Do In Slovenia tour company. Our tour guide, Doman, was a great story teller and it made the drive to and from the cave and castle go by quickly. He gave us a lot of good historical information about the cave and castle. Note: It's important to wear stable/slip resistant shoes or this tour. Some of the areas are a bit slick and there are some steep steps to climb.

Positive experience - Friendly people, clear communication, everything goes as described. During the trip stories and anecdotes about the environment and culture are told. I travel alone and choose this kind of group stuff, among other things to have contact with fellow travelers. The way the trip was organized, an effort was made to involve everyone who wanted to, and that is appreciated.

Beautiful Cave - This tour was amazing I will say that once you get on the train to take you to the cave please hold on to your backpack or bags. I took my backpack off and sat it on the seat for just a second and the train took off and my backpack fell between the open of the back seat. It had my cameras in it and I knew for sure it was lost forever. I reported it. and at the end of the tour, they had retrieved it. The cave tour was good I walked it along and took my time, I was so happy no stairs were involved so if you have knee issues this is good, It was a lot of walking but it's beautiful. This is a must-see. The castle was great too,
