Cuxhaven is a seaside town on Germany's North Sea coast. Brightly colored shelters dot its sandy beach. The Kugelbake, a wooden navigational tower, stands at the mouth of the Elbe River. The UNESCO World Heritage Wadden Sea Visitor Centre Cuxhaven has a nature trail and exhibits on the area's tidal flats and wildlife. The port is a gateway to the nearby tidal island of Neuwerk and the small Heligoland archipelago.
