Mauldre (rivière) walks

This circular hike in the Beynes forest takes you past several underground gas storage sites. You will then cross the village of Saulx-Marchais, passing by its old church and town hall before crossing the fields to reach Neauphle-le-Vieux and the Mauldre river. Return to the starting point via the Beynes forest.

A hike on the slopes of both banks of the Mauldre, a tributary of the Seine between the Plaine de Versailles and the Mantois. The route, consisting of two loops, alternates between residential areas, forests and fields. A rich heritage, partly linked to water, can be discovered along the way: an old fortified castle, old mills, a siphon bridge, farm buildings, a church, etc.

After exploring Maule and its heritage, you will climb through the woods and walk through the countryside to reach Aulnay-sur-Mauldre. From there, you will follow the Mauldre and its recent meanders back to the starting point.

This walk will first take you on a journey of discovery through the heritage of this district of Aubergenville and Épône, an avant-garde holiday resort created in the 1920s. On the way back, you will walk along the Mauldre and Giboin rivers to reach the "beach".

A walk on the plateaus above the Mauldre valley. A rolling landscape as far as the eye can see accompanies you throughout the hike.

This short walk will take you through a small valley to Vaux-les-Huguenots, where Protestants fled persecution, then on to Aigue Flore Park in La Falaise, where you’ll cross the River Mauldre and come across various little heritage gems.

Montainville is situated in the centre of the Yvelines department. The commune’s territory extends across the eastern edge of the Mantois plateau and the western slope of the Mauldre valley. The village site forms a promontory bounded by two valleys named after their springs: the Serpe valley to the north and the Orme valley to the south.

This is a walk around Pontchartrain, passing through Villiers-Saint-Frédéric, Neauphle-le-Vieux, Mareil-le-Guyon and Tremblay-sur-Mauldre. You will follow restored footpaths amongst castles, rivers and fields.

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.

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.
