Presentation

The Upper Bièvre Valley is a region comprising eleven municipalities in the departments of Yvelines and Essonne. This site, designated on July 7, 2000, runs along the Bièvre River, which originates in Guyancourt and flows into the Seine in Paris.

This natural area is rich in heritage and has the advantage of being close to Versailles and Paris. The towns through which the Upper Bièvre Valley passes are: Guyancourt, Buc, Les Loges-en-Josas, Jouy-en-Josas, Vélizy-Villacoublay, Bièvres, Saclay, Vauhallan, Igny, Massy, and Verrières-le-Buisson.
