A number of long-distance bus lines have opened up in recent years, including the Post Bus, Eurolines, and Flix Bus. Regionally, the bus system is partially owned by and coordinated with the German Railways, so it's easy to reach every corner of the Black Forest by bus and train. Regional bus stations are usually at or near the train station. For more information, contact the Regionalbusverkehr Südwest (Regional Bus Lines) in Karlsruhe.
