Donjon de Maurepas walks

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.

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 stage is the last of the old GR®1 route. The departure point is at Villiers-Saint-Frédéric, at the RER station. The entire route is rural. It passes through several villages, including Saint-Germain-la-Grange, Thiverval-Grignon and Davron. There are two notable churches: those of Davron and Thiverval-Grignon, not to mention Feucherolles. This is an undemanding section that allows you to finish the GR®1 at a leisurely pace.

Fourth stage of the Grand Tour de l'Île-de-France on the GR® 11 and start of the clockwise circular section.This stage takes place entirely in the Yvelines department, connecting Villiers-Neauphle-Pontchartrain station to Orgerus-Béhoust station, crossing the Beynes forest and the agricultural landscapes of the Yvelines. The route runs alongside the Avre aqueduct, which supplies drinking water to western Paris.

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.

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.

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.
