Wide/Continent-Wide Bus Travel like Greyhound?
There is no national or private bus company like greyhound. There are, nevertheless, a few lines run by the European railroads or private companies. Some of the lines you can find in the Kursbuch. On many lines there is only one bus every day or even week. Some airport bus lines have real service. A return ticket Hamburg-Paris costs about DM 150. In towns with many foreign workers there might also be some bus services to the South, but you have to be a local to know about it.
