Stockholm has regular ferry lines to Helsinki and Turku in Finland (commonly called "Finlandsfärjan"); Mariehamn, Åland; Tallinn, Estonia; Riga, Latvia, and to Saint Petersburg in Russia. The large Stockholm archipelago is served by the archipelago boats of Waxholmsbolaget (owned and subsidized by Stockholm County Council). Additionally, there are many for-profit private companies offering tours and regular service in the archipelago.
