Postojna cave and Predjama castle tour

Our guide Branko was very enthusiastic and informative. He really made the difference between an average tour and an excellent tour and ours was truely excellent. He gave us loads of information regarding the cave, the castle and Slovenia in general. I highly recommend this tour. Don't worry about finding the bus, once you're at the pickup location they'll find you.

Slovenian highlights

Thomas was a friendly and informative guide. The places we stopped at were well worth a visit, particularly the caves which were absolutely stunning. However, whilst it IS stated in the detail, we hadn't fully appreciated that entry fees were on top of what we had already paid - making this a very expensive day. With hindsight, we would have sought our own transport and visited the caves and Lake Bled independently

Be prepared....

Yuri was a terr1fic guide. He was a wealth of information regarding the areas we drove through getting to he caves and was extremely entertaining. I will say the actual tour through the caves and the associated walking, traversing inclines and declines, was somewhat strenuous. For some reason, I thought the train ride was the bulk of the activity, but, I was so wrong. That being said, I am very glad we went as it was beautiful, and very interesting.

Amazing day

Amazing trip. The castle and then the caves. Due to foggy weather conditions in Ljubljana i thought that it wouldn't be worth going. Out further the weather changed we were able to see the scenery, then onto the castle where we walked round. From there onto the caves. This was all made very spectacular by our super guide Nate. He was very informative. Telling us the history and the dates of what had occurred in the past. I would highly recommend it.
