Loing
The Loing is a long river in central France, a left tributary of the Seine. Its source is in Sainte-Colombe-sur-Loing, in the south of the Yonne département.
The Loing flows into the Seine in Saint-Mammès, near Moret-sur-Loing. The part of the Briare Canal between Rogny-les-Sept-Écluses and Montargis runs parallel to the Loing. Its main tributaries are the Ouanne, the Aveyron, the Puiseaux, the Solin and the Lunain.
