Église Saint-Germain de Paris (Magny-les-Hameaux) walks

Thirty-third and penultimate stage of the Grand Tour of Île-de-France via the GR®11, almost entirely in the Yvelines department.It starts in Saint-Rémy-lès-Chevreuse and reaches Coignières after climbing up the Yvette valley and crossing the Haute Vallée de Chevreuse Regional Nature Park with its rich natural and architectural heritage, just a stone's throw from Paris and its inner suburbs.

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.

The Bièvre Valley is undoubtedly one of the best places for hiking in the region. Indeed, in summer it is a succession of ponds and lush green landscapes. This hike takes you through the most interesting part of the valley, featuring a succession of five remarkable ponds. You can then round off your day with a visit to Versailles, adding a touch of history to the route.

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 south-north crossing for a very diverse route. Forest passages alternate with passages between fields. Water is abundant, with several rivers, the Yvette, the Marette and the Bièvre, and the Étangs de Montbrond in their green setting.

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.

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.

This hike starts in Gif-sur-Yvette and takes you to the heights of the Saint-Aubin and Vallée Bonnard channels, following the Yvette river and returning via La Mérantaise, passing through the Bois d'Aigrefoin, the Saint-Aubin communal forest and the Coupières basin.

An alternative route to the first section of the Chemin Charles Péguy. It bypasses Limours and instead showcases the Hurepoix region. Discover the beautiful village of Forges-les-Bains and a route through stunning countryside.

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