Loved this tour of Postojna Cave and Predjama Castle with To Do in Slovenia. Matej was a great guide, and the cave was really impressive, while Predjama Castle was such a unique place to visit. Everything was smooth and well organized, and it was a great way to see more of Slovenia.

Prompt pickup. Friendly,...

Prompt pickup. Friendly, organised and informative guide. The caves are particularly touristy but are well organised and therefore still worthwhile. some more elderly tourists struggled a little with the walk at the caves and the steps at the castle. We found the castle, particularly interesting but at peak season, I would imagine it is chaotically busy.
