Upper Austria is integrated into the network of international scheduled bus services. Buses run regularly from neighbouring countries, especially to Linz.
The Flixbus company integrates Linz and thus Upper Austria into its route network from Munich. The Westbus runs regularly between Prague and Linz and also connects the provincial capital with Graz and Klagenfurt. As a destination and departure point for the international Eurolines buses, Upper Austria is also integrated into the widely ramified route network of this transport provider.
