I have an interrail global pass and from this part of the trip, I have to go from Slovenia to Thessaloniki. I am super flexible. I am basically looking for the cheap and awesome. My plan was passing through Croatia, Bosnia and Herzegovina, Serbia, Macedonia and end up in Greece but I don’t seem to find train connections there (I am starting to wonder why..).
Interrail says that there are trains in those countries. I read somewhere that I have to do so through that country rail company. Other say it is better by bus (I prefer things that are included in the global pass as I already paid for it, but maybe that is the solution). My worry is that I cannot find anything because there is no train or that I go somewhere and moving from there to the next country is not possible by train.
Does someone has a good suggestion?
