This route follows thePR®10and 13 trails and the Promenade de l'Yvette. It has been chosen to avoid as much as possible the busy roads crossing the Basses Roches district in Villebon. Only the crossing over the A10 motorway via the viaduct is unavoidable, but it is short (200 m) and the pavement is wide. The rest of the route is pleasant along the Promenade de l'Yvette, the paths in the plain and around the Étang de Saulx-les-Chartreux.
