There are two ways from Ljubljana toward south, either via Zagreb or via Istria (north Croatian coast).^^
Thanks a lot for all this this info and all the help you're giving me.
First of all I'm going to tell you a bit about our journey and then I'll give more details.
We arrive to Venice next wednesday, 11th june and we come back to Spain next 25th june also from the Venice airport. We have in mind to visit Liubliana (Slovenia) and finish our trip down in Dubrocknick, maybe also visit Montenegro. And finally go back to Venice.
Our big problem is what to visit in the way, and how to organize time and places. Therefore I would be greatfull if you could give me this kind of advice, including recommendations on restaurants and afordable hotels. It would be great if you could also tell us which is the best transport to travell from one place to another. We are interested in architecture, art, sightseeing and of course to rest on the beach.
Thanks again, looking forward to read your posts.
The best way to commute within Croatia is by buses (frequent and reliable); trains are scarce (good if you go directly Zagreb to Split for example).
Via Zagreb: Ljubljana to Zagreb by train, from Zagreb toward south (Plitvice Lakes national park) by bus, further south also by bus.
Via Istria: a bus to Rovinj, than to Pula; take a SplitTours ferry Pula – Mali Lošinj - Zadar (does not run every day, other option is bus), continue Zadar to Šibenik, Split (stopover in Trogir) by bus; ferry/catamaran to Hvar island; ferry/catamaran Hvar to Korčula, ferry/bus from Korčula to Dubrovnik.
Pula - Zadar
You can make day trips to Montenegro (Kotor Bay) from Dubrovnik by bus
To get back to Venice take a ferry Dubrovnik to Bari in Italy, than the train up to Venice.
This is just a sketch, of course. If you’re on a budget, the cheapest accommodation is to book a private room. Do it through tourist office, you’ll find these in all city/town centers – don’t take the room offered at bus stations or ferry ports directly by owners (these are usually also good, but the other option is safer).
