The Orge is a 53-kilometre (33 mi) long river in France, left tributary of the Seine. Its source is in the village Saint-Martin-de-Bréthencourt. Its course crosses the départements of Yvelines and Essonne. It flows northwest through the towns of Dourdan, Saint-Chéron, Breuillet, Arpajon, and Savigny-sur-Orge, finally flowing into the Seine in Athis-Mons, south of Paris. The towns located on the banks of the river usually have s/ Orge added to their name (i.e. Épinay-sur-Orge, Longpont-sur-Orge, Villiers-sur-Orge). The Yvette is a tributary of the Orge.

Promenade de l'Orge
Many of the local councils maintain parks on the banks of the river. A syndicat has been formed to link the parks of 32 communes. The result is a footpath that ends in Athis-Mons, where the Orge flows into the Seine. Bicycles are allowed on the footpath although pedestrians have right of way. Motorised vehicles are not allowed (although electric bicycles will probably not be a problem).
