I would like to travel from Skopje to Thessaloniki in August. I know that the train is not an option on this route so I will have to take the bus. However, I cannot seem to find any information online on International busses departing from Skopje. I did find a Rule Turs bus bookable on busticket4.me or getbybus on Tue, Thu, Sat: Skopje - Thessaloniki 8.30-13.05, but I don't know how reliable these sites are as I could not find a (working) site of Rule Turs itself. Does anybody have more information/experience regarding this route?
Thank you in advance.
