Arcades de Buc walks

This is the upstream section of this series of three walks dedicated to the Bièvre. A very pleasant route along the river and its ponds, in a setting that is mostly bucolic. A walk from station to station, the length of which can be adapted according to conditions or preference.

A varied route, more than half of which is through woodland. Crosses a village via footpaths, a plain with views, and a pond. The surface of the route is in good condition, except for the embankment, depending on the height of the grass. A pleasant little walk well worth discovering.

This marked GR® route around the Île-de-France region (with a few forays into neighbouring departments and regions) complements its "little brother", the GR®1, by forming a circular route around Paris, generally with a slightly larger radius. It follows the same overall pattern: first, a radial section starting from Paris (more precisely from the Pont d'Austerlitz, near the former confluence of the Bièvre and the Seine), going up the entire Bièvre valley, then continuing to Villiers-Saint-Frédéric, in the Yvelines. From there, it is a circular route that loops around the Île-de-France region, close to its borders with neighbouring regions. The route passes through beautiful regions, often untouched by intensive urbanisation, regional nature parks and other protected natural areas, and takes in some architectural wonders.

Second stage of the Grand Tour of Île-de-France via the GR®11, from Massy to Saint-Cyr l'École, behind Versailles.This stage, more bucolic than the previous one, consists of continuing up the Bièvre river in its valley, where it is almost entirely in the open air. Arriving near its source in Guyancourt, the GR® leaves the valley and continues towards Saint-Cyr-l'École.
