Seine

The Seine is one of the most famous and important rivers in France. It rises in the Bourgogne-Franche-Comté region on the Langres Plateau and flows approximately 777 kilometres northwestward before emptying into the English Channel near Le Havre. Geologically, the Seine mainly traverses limestone and chalk formations of the Paris Basin, which formed during the Cretaceous and Tertiary periods. These soft sedimentary rocks have shaped the characteristic gently undulating hilly landscape of the Île-de-France and allow for the river’s typical calm course with its many meanders.Historically, the Seine has played a central role as a trade and transport route since antiquity. The Celts and later the Romans already used the river, and in the Middle Ages, Paris became one of Europe’s most important cities thanks to the Seine. In the 19th and 20th centuries, the river was regulated several times to improve navigation and reduce flood risks.Today, the Seine is primarily a place for recreation and leisure. In Paris, the riverside promenades—especially the Seine banks between the Pont de Sully and the Pont d’Iéna (protected as a UNESCO World Heritage Site)—invite long walks, picnics, and cycling tours. In summer, parts of the banks transform into “Paris Plages” with sandy beaches, deck chairs, and cultural events. Boat tours on the Bateaux-Mouches are among the most popular leisure activities and offer unique views of famous landmarks such as Notre-Dame, the Louvre, and the Eiffel Tower. Canoeing, kayaking, stand-up paddling, and fishing are also possible on many sections. Outside Paris, the Seine loops in Normandy invite visitors to idyllic cycling tours, houseboat holidays, and relaxed fishing or picnic excursions. The river and its banks form a vibrant leisure space that attracts both locals and tourists alike and invites everyone to enjoy the French way of life.
