Église Saint-Martin (Chevreuse) walks

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 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.

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.

A hike from station to station with a water theme! In the Haute Vallée de Chevreuse Natural Park and then in the Rambouillet Forest, this is a pleasant route, mostly shaded, along ponds, small canals and a charming river, the Drouette.

A hike from station to station that will take you through the forest of the Haute Vallée de Chevreuse Regional Nature Park. Ponds, castle, forest, ramparts and museum: everything you need for a wonderful day out with family or friends.

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

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 hike from station to station, mainly through forest. Although located in an urban setting, this route takes you through green (in season) and peaceful areas. The Chêne des Missions oak tree and the Étang du Trou au Gants pond are two beautiful points of interest.

A hike from station to station that takes you on a rollercoaster ride through the Fausses-Reposes Forest and Saint-Cloud Park. Along the way, you can enjoy the Étangs de Ville-d'Avray, the park's ponds and statues, and a superb view of the Val de Seine and Paris.

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.
