Auvergne-Rhône-Alpes, France
The Rhône; Walser: Rotten [ˈrotən]; Italian: Rodano [ˈrɔːdano]; Arpitan: Rôno [ˈʁono]; Occitan: Ròse [ˈrɔze, ˈʀɔze]) is one of the major rivers of Europe and has twice the average discharge of the Loire (which is the longest French river), rising in the Rhône Glacier in the Swiss Alps at the far eastern end of the Swiss canton of Valais, passing through Lake Geneva and running through southeastern France. At Arles, near its mouth on the Mediterranean Sea, the river divides into two branches, known as the Great Rhône (French: le Grand Rhône) and the Little Rhône (le Petit Rhône). The resulting delta constitutes the Camargue region. The Rhône is one of the four major rivers taking their source in the Gotthard region, along with the Reuss, Rhine and Ticino.
