Baltic Sea

Large cruiseferries sail in the Baltic Sea between Finland, Åland, Sweden, Estonia, Latvia and Saint Petersburg, Russia. In many ways, these ferries are like cruise ships, but they can also carry hundreds of cars on car decks. Besides providing passenger and car transport across the sea, Baltic Sea cruise-ferries are a popular tourist destination unto themselves, with multiple restaurants, nightclubs, bars, shops and entertainment on board. Helsinki was the busiest international passenger ferry port in the world in 2017 with over 11.8 million passengers whilst the second business international ferry port, Dover, had 11.7 million passengers. The Helsinki- Tallinn route alone accounted for nine million passengers. In 2022 the port of Helsinki had almost 8 million passengers, of which 6.3 million travelled between Helsinki and Tallinn. Additionally many smaller ferries operate on domestic routes in Finland, Sweden and Estonia.

The south-west and southern parts of the Baltic Sea has several routes mainly for heavy traffic and cars. The ferry routes of Trelleborg - Rostock, Trelleborg - Travemünde, Trelleborg - Świnoujście, Gedser - Rostock, Gdynia - Karlskrona, and Ystad - Świnoujście are all typical transports ferries. On the longer of these routes, simple cabins are available. The Rødby - Puttgarden route also transports day passenger trains between Copenhagen and Hamburg, and on the Trelleborg - Sassnitz route, it also has capacities for the daily night trains between Berlin and Malmö.
