This busy port city, where the Weser empties into the North Sea, belongs to Bremen, about an hour to the south. You can take in the enormity of the port from a promenade, which runs its length. In addition to being a major port for merchant ships, it is the biggest fishery pier in Europe, which means that the promenade is lined with excellent seafood restaurants. A brand-new hotel and conference center has just opened on the harbor.
