All the sites were interesting and the time spent at the sites was appropriate. Postjana cave was an incredible experience. Irina was a great guide. We gained a lot of information about Slovenia from many different perspectives during the day.

We had a wonderful day. The guide was fantastic. It's definitely worth getting the combined castle and cave ticket. Thank you so much!

Amazing tour! Both the castle and the cave were once in a life time experience for us. I definetely recommend this tour for those who are travelling to Slovenia for a couple of days. It is just 1 hr drive from Ljubljana. It is not possible to understand the spectacularity of the cave from the photos, you need to experience it. You take a tour in the cave with a guide, first couple of km.s with a train and then walking. Very well organized tour. And thank you to our own guide who gave us lots of lots of information about the Slovenia.

David was a most interesting guide. He had a kind personality too and I would highly recommend this tour. As tour guides go, he was the best on all levels.
