BALKAN VIATOR

This website from the British company GoViator Ltd provides bus timetables for the Balkan countries (except Romania and Moldavia). It is relatively accurate for North Macedonia. Some city-to-city connections and almost all local village services are omitted, as are fares, which are not shown. But it's very useful for finding out about bus schedules, companies and frequencies, as well as links to neighboring countries, cab companies, car-sharing and trains.
