If someone wants to properly swim in the sea, perhaps you are not right in Cuxhaven. When the tide comes, the dragons guarding the beach entrance (you must pay) even leave their posts. Because the main attraction in the German North Sea is the Watt.
Watt – for endless ankle-deep walking in water, meditation of the boundless sky reflected in the endless water surface, calming the nerves, searching for small sea creatures and confronting crabs. Children can hang around on this shore for an infinitely long time, picking out someone, building castles and getting covered with a layer of mud as much as possible.
Watt – shallow water of sand and clay, in some places stretching for kilometers. Even at high tide, hundreds of meters offshore, you may lack depth for swimming. The bottom topography is clearly visible on satellite maps.
