The city runs north–south along the eastern bank of the Weser River, and most of Bremerhaven's main sights are conveniently located around Havenwelten, which comprises Neue Hafen (New Harbour) and Alter Hafen (Old Harbour).

To get there from the Hauptbahnhof, board any city bus leaving from in front of the Sparkasse building outside the station and disembark at the ‘Havenwelten’ stop, about 1.7km northwest. The Schaufenster Fischereihafen, which has a few sights and some excellent fish restaurants, is 2km southwest of the station (take bus 505 or 506).
