5.00We went to the castle and the cave system, which was great. The castle was really interesting, and it was crazy to imagine people building it back in the day. You can snap some real good pictures there. The cave system was unbelievable, definitely worth seeing when you're in Slovenia. I've never seen anything like it, it was like going to another planet. The trip, in its entirety was fantastic, we were sorry to leave but will be back in the future. I'd also like to mention Anna the lady that drove us from Bled, 2 hours to the castle and cave system. She was absolutely wonderful, we can't say enough good things about this lady. She was polite, welcoming and very friendly, and we talked and laughed with her the entire journey. In fact, she was so memorable and nice to be around that we are planning to book on her skiing project in the future, just to see her again. Anna we loved you hope to see you again soon, love Ewan and Olga (the engaged couple) xxx
Worthwhile trip!

4.00Despite being late due to traffic Anna managed to get our day back on track and took got us to the castle/cave in good time. The dual ticket which seems a bit pricey at first €38 each it is actually really good value to see the vast cave and unique castle. Overall it was a really good day.

2.00The cave and the castle are great! The tour before, between and after the two however is not. Our guide was a friendly guy, but besides being the driver there was little for him to do. There was a guided tour at the cave and an audio tour at the castle. So basically you’re paying for a shuttle that takes you from Ljubljana or Bled to the caves, castle and back... the bus will get you there much cheaper.
