Étang de la Pimardière walks

Fifth stage of the Grand Tour of Île-de-France on the GR®11, connecting Orgerus-Béhoust station to Mantes-Station, still through the Yvelines. This is a northbound route that joins the Seine valley at Mantes-la-Jolie, descending the valleys of the Flexanville and then the Vaucouleurs rivers. The route follows both paths at the bottom of the valley and paths on the adjacent plateaus.

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 fairly easy walk from station to station, the first part of which is through woodland where you can admire superb specimens of various species of deciduous trees, particularly beeches and oaks, which are certainly over a hundred years old. You also pass close to the Alluets-le-Roi telecommunications centre and its many antennas of all types.The second part, which is more varied, includes a visit to the ruins of Abbecourt Abbey and the centres of the villages of Orgeval and Villennes-sur-Seine with their churches. The walk ends with a pleasant stroll along the banks of the Seine.

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 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 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.

Sixth stage of the Grand Tour de l'Île-de-France on the GR® 11, linking Mantes-Station railway station in the Yvelines to the village of Genainville in the Val d'Oise, in the heart of the French Vexin. This stage is the first part of a two-day route, the aim of which is to connect Mantes-Station railway station to Chars railway station, further north-east in the Val d'Oise.The stage begins in Mantes-la-Jolie in the Seine valley and heads north through the south-western part of the Vexin Français Regional Nature Park, quickly passing from one of the lowest points in the region (crossing the Seine, at ~18 m) to one of the highest points (the beech forest at Villiers-en-Arthies, at 205 m).The French Vexin, with its unspoilt agricultural and wooded landscapes, is a magnificent region where it is very pleasant to hike.
