Our guide Primož was the absolute best! He was not just punctual and friendly but he was full of history, funny stories and so likeable by our whole group. He went above and beyond any of our expectations. He even brought us to 1,000 year old castle for lunch since we asked for a recommendation. It was unreal. Primož, thank you making our time in Slovenia so fun!
Our guide, Mihael (Mike), took us to the caves, the castle in front of the cave, and then for lunch in a local restaurant. Mike was very knowledgeable and friendly. The caves and castle were beautiful. Bring warm clothing, the caves are chilly! Definitely recommend this tour with Mike if you are going to Koper.
