The majestic St. Lawrence River, which links the Atlantic Ocean to the Great Lakes, runs across the entire territory of Québec and is bordered by numerous cities and villages.
Numerous ferries offer year-round or seasonal service on the St. Lawrence River and other major waterways (the Saguenay, Richelieu and Outaouais rivers). A ferry also links Prince Edward Island to the Îles-de-la-Madeleine, while a passenger-freight ship serves the entire Basse-Côte-Nord region between Havre-Saint-Pierre, Île d'Anticosti and Blanc-Sablon. Reservations are recommended, particularly during the peak season.
Thanks to the Quebec Marine Association new voluntary classification program, some 50 of the province’s recreational marinas now feature one- to five-golden anchor ratings. This organization also runs the Eco-Marina certification program, as well as the nautical station program, a network of 15 of Québec's main marine destinations.
