The longest river in France is the Loire River, which flows for approximately 629 miles (1,013 kilometers) from its source in the Massif Central region to the Atlantic Ocean. The Loire River is often referred to as the "last wild river" in France, as it is relatively untouched by human development along much of its course. It is known for its picturesque scenery, historic chateaux, and diverse wildlife habitats. The Loire Valley, through which the river flows, is a UNESCO World Heritage Site and a popular tourist destination in France.
