Fondation de Coubertin walks

A hike from station to station where you play leapfrog with the Yvette River! The route is mostly close to the river and crosses a few woods and pretty parks, including the one in the western part of the Paris-Sud University campus.

A hike from station to station, yo-yoing between the Yvette valley and the Saclay plateau, with a few fairly steep hills. After a mostly wooded route with some elevation, you cross Gif-sur-Yvette and then walk along a wetland area framed by two rivers. You climb back up onto the plateau, near the Paris-Saclay University campus. After visiting the old Troche quarry and walking along the edge of the plateau, you descend back into the valley.

The upstream part of this series of three hikes devoted to the Bièvre river. A very pleasant walk along the river and its bodies of water, in a mostly rural setting. A hike from station to station, which can be used to adjust the length depending on the weather conditions or desires of the hikers.

A varied hike where you gain altitude. First, you climb up to the Saclay plateau and walk along the university campus before gently descending into the Yvette valley through the forest. We climb back up the other bank and cross the Gif-sur-Yvette forest from east to west. After an urban section, we walk between fields before descending back into the forest to Saint-Rémy-lès-Chevreuse.

This is the third stage of the GR® 11 Grand Tour of Île-de-France. It continues through the Yvelines, between Saint-Cyr station and Villiers-Neauphle-Pontchartrain station. This stage completes the 'radial' part of the GR® starting from Paris and joins the circular loop that circles the region from Villiers-Saint-Frédéric. The route passes through increasingly large wooded areas as you approach the countryside.

A hike from station to station that takes us to the source of the River Yvette and then up and down through the woods that frame its valley. The route crosses the Maincourt Marsh and then an area of rocky chaos. The forest trails are interspersed with villages and hamlets rich in heritage.

Hike connecting Igny (Essonne) to the Palace of Versailles. The route follows the Bievre, and 80% of the route is on roads through forests. A calm, cool walk with scenery that will leave you with a unique souvenir.

A route from station to station, through the woods and with some elevation gain. Walking or jogging.

This hike follows the route of the T12 tram-train, connecting Massy-Palaiseau to Évry-Courcouronnes, and allows you to discover a varied landscape combining urban areas, natural spaces and neighbourhoods undergoing rapid change. The route takes you along the greenway that runs alongside the T12, between Épinay-sur-Orge station and the Évry-Courcouronnes terminus, offering a pleasant and safe section for pedestrians and cyclists. This walk offers an immersion in the areas served by this new line, with opportunities to stop at the various stations to fully enjoy the local heritage and green spaces.

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.
