In addition to the regional trains, there are some bus companies that offer trips throughout Germany and also abroad. It is a good idea to compare prices. “Flixbus/Mein Fernbus”, “Postbus” or the “Berlinlinienbus” are examples of long distance bus companies. It is best to book the trips in advance online.
Trips from Bremen start from the stop “ZOB” on Bremenweg next to the main train station (see map).
