Hello, I’ll be traveling from Netherlands to Belgrade, Serbia this summer. My final destination is Athens, Greece, but I do not know how to go about. I understand taking the train from Belgrade to Athens is not possible as there is no connection, I know there is a bus but I would rather travel by train as soon as I entered Greece.
I was thinking to take a bus from Belgrade to Thessaloniki and then from Thessaloniki a train to Athens, however, this does not show up in the DiscoverEU app. I can not figure out if these trains are actually running. Can someone give me some advice?
