Amazing - Fabulous experience! We were the first South Africans our driver has met in all his years of working. Never thought id ever go through a cave in a train and see such beautiful formations. The castle was magnificent. I loved Slovenia nice to be In a quieter country away from the hustle and bustle of the other places I've been to. Bring a jersey the caves are cold!

Interesting, informative, and kinda cool - Both sites visited were pretty cool to see, and Ernest, our guide, was interesting, informative, and funny. He made it an overall fun experience.

Fabulous Tour! - Our tour guide, Ernest, was great! He was funny and informative on all things Slovenia. The caves were breathtaking, and the castle was very cool! Please read the tour instructions and bring a sweater for the caves (they are chilly!) and your passport! We were on a tour with people who forgot both and without the passports, got held up at the border. Don't be those people!

Visit not to be missed under any circumstances - Our guide Ernest (former ski jumping professional) was fabulous: his professional knowledge, his enthusiasm, his listening to our requests and his kindness. Recommended.

Excursion in Trieste - We loved the caves not as much the castle. HOWEVER- we expected ( as did others) a group of about 20 and it was over 50!! Plus the tour guide basically opened the doors handed us tickets and that was it! Hard to find him or even know who group was! Although we loved the caves. We were VERY disappointed with the organization of this excursion!!! We have done others through Viatour that have been run very professionally but this definitely not!
