France is a nation of varied landscapes, ranging from coastal lowlands and broad plains in the north, to hilly uplands in south central France, to lush valleys and towering, snow-capped Alps in the east. Mountainous and hilly areas lie on nearly all of France’s borders, creating a series of natural boundaries for the country. Only the nation’s northeastern border is largely unprotected. Several major rivers drain France, including the Seine, Loire, Garonne, and Rhône.
