Boat and Ferry Travel
Ferries travel daily from Gdańsk and Gdynia to Karlskrona and Nynashamn, Sweden. You can also arrive by cruise ship, Gdynia being the main international port in northern Poland for cruise ships. In summer there are pleasure cruises on the Motława River and the Baltic, and an hourly water-bus service links Gdańsk with Sopot and Gdynia, via Westerplatte and Hel. Polferries and Unity Line operate also between Świnoujście and Ystad (Sweden) and Copenhagen (Denmark).
