Brilliant tour, our guide was very efficient and informative. Highlight of my time in Slovenia as I’ve never seen anything like the castle and caves
This tour was very well planned and kept us interested throughout. Our guide was friendly, knew a lot, and made it fun. I'd definitely recommend it; it's worth it!
