The bridge over the Orge, near the Bassin du Breuil in Épinay-sur-Orge, is a charming passage that offers a peaceful view of the river and its green banks. Surrounded by trees and paths, this bridge is an ideal place for a contemplative break. The murmur of the water and the serenity of the landscape invite you to relax.

Hello everyone, be careful, several waypoints (notably 5) do not exist or no longer exist. I really struggle to follow this tour.

It's shaped very carefully. In addition, it is entirely possible to cross the terrain in XC, bypassing the worst springboards.

Be careful, some forest roads have been closed with barbed wire certainly by hunters, you can easily bypass these barriers. It is not a private forest but a state forest...

Like the nearby Fauvettes viaduct, the Montjay tunnel once served as the old Paris-Chartres railway line. In the middle of the communal forest of Bures-sur-Yvette, it punctuates the straight and rolling line leading to the viaduct.
