There are a lot of ports and harbors in France and here are the largest.
It is the second largest city and largest port in France. Many of the buildings around the port were damaged or destroyed during World War II, but have been rebuilt to mimic the pre-war charm of the area. Ships dock in two main areas of commercial piers in Marseille, both north of the Vieux Port area. The bay flanked by Fort Saint-Nicolas and Fort Saint-Jean shelters the Castle of If, from Count of Monte Cristo fame.
This port was established in 1517 by King Francis 1. It is accessible 24/24 and has the capacity to host the biggest cruises ships. The port has 3 dedicated cruise berths and can accommodate up to 4 cruise ships. With the extension of the cruises season, Le Havre is also a safe shelter port in case of bad weather conditions.
It is the third largest port in France. It is also an industrial city, heavily dependent on the steel, food processing, oil refining, ship building and chemical industries. You should definitely visit Musée des Beaux-Arts and Belfry Saint Eloi in Dunkerque.
Situated in in western France and a seaport on the Bay of Biscay, a part of the Atlantic Ocean. It is the capital of the Charente-Maritime department. La Rochelle is an important port for fishing in the Atlantic or for trading and commerce. Also, it is a big harbor for pleasure boats and the whole industry for boating.
Saint – Tropez
Located on the French Riviera, before world war it was a powerful military and fishing town. The port of Saint – Tropez services only well-known regattas and it is not a commercial marine spot. Choose to go at the end of September, when a regatta is held in the bay of Saint-Tropez (Les Voiles de Saint-Tropez).
Port of Strasbourg
The Autonomous Port of Strasbourg handles exports/imports of cereals, agricultural products, oil products, gravel, machines, etc. Yet river tourism has also developed there: cruises on the Rhine, tours of Strasbourg by pleasure boat or lounge boat with Batorama.
