Szczecin in North-Western Poland has a deep commitment to sail training. Discover the Underground City Trails: a network of bunkers from WWII with their unique atmosphere. If you're more of an outdorsy type, take a canoe along the Odra river or explore Bukowe Hills which hide the ruins of old bridges and are home to numerous boars and deer. Visit one of many museums or the Castle of Pomeranian Dukes or the beautiful rose gardens.
Cuxhaven is a North Sea port town in Germany, home to an important fisherman's wharf, and one of the largest sea side resorts in Germany. Cuxhaven is a quiet place, so don’t expect too much action. But its beaches, the small castle Ritzebüttel, and the ship wreck museum are well worth your time. Take a walk over the promenade and gaze at the passing ships, go for a nice dinner in one of the many restaurants, or dig up your swimming trunks and spend a nice afternoon at the beach.
