Departure from Bures-sur-Yvette (Essonne)
A loop in the Chevreuse Valley, with magnificent landscapes, in a wooded and rural setting close to Paris. The first part is a walk through the woods on the plateau overlooking the Yvette Valley. The return journey, parallel to the outward route, is mainly on flat ground. Most of the walk is well shaded and flat, but there are also some fairly steep ascents and descents. The area is very popular with walkers and mountain bikers, but it is well worth a visit.

Departure from Gif-sur-Yvette (Essonne)
A south-north crossing offering a very varied route. Sections through the forest alternate with stretches across fields. Water features are plentiful, with several rivers—the Yvette, the Marette and the Bièvre—and the Étangs de Montbrond set in their lush green surroundings.
(Warning) The route is cut off at the point (12) due to works on Metro Line 18 (as of March 2026). A diversion is under consideration. Please refrain from undertaking this hike until further notice.
