Château du Mesnil-Saint-Denis walks

Hike along the Yvette river, with its wash houses, passing by the Château de la Madeleine. The route also passes through a forest in a former sandstone quarry.

This is the thirty-fourth and final stage of the Grand Tour of Île-de-France via the GR®11. It starts in Coignières and ends in Villiers-Saint-Frédéric, where the radial section of the GR® coming from Paris meets the circular section, which will therefore be completed here. The route follows, more or less closely, the course of the Mauldre River, passing through Bazoches-sur-Guyonne, Mareil-le-Guyon and Neauphle-le-Vieux.

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.

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.

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.

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.

Hike in the Rambouillet forest, but in the lesser-known and less frequented part. The Rochers d'Angennes are impressive; you don't expect to find yourself in a blue-collar atmosphere in this place. Hike from station to station with a fast TER at the end, if returning to Paris.

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.
