Gare de Santeuil-Le Perchay walks

This is the eighth stage of the Grand Tour de l'Île-de-France on the GR®11, starting from Chars station in the Val d'Oise and heading towards Bornel-Belle-Église station in the Oise, through the north-eastern part of the French Vexin and the borders of the Pays de Thelle. This stage is unique in that it runs along the border between the Val d'Oise and Oise departments, with roughly 50% of the route on each side. The proposed itinerary passes through the Buttes de Rosne, the highest natural point in Île-de-France, although it deviates slightly from the GR® for this.

A hike from station to station with the Oise as the guiding thread. You will cross several wooded parks and follow the river for a long time, mostly on a right of way. At the end of the route, the passage through Auvers-sur-Oise is an opportunity to evoke the famous painter Vincent Van Gogh.

A lovely walk along the banks of the Seine, passing through pretty villages such as Evecquemont. The starting point and finishing point are two stations on the same SNCF line.

Seventh stage of the Grand Tour of Île-de-France on the GR®11, starting from the village of Genainville, in the heart of the French Vexin, and heading towards Chars station further east. This stage goes hand in hand with the previous Mantes-Genainville stage, with a night in Genainville or the surrounding area necessary to walk between Mantes and Chars stations. This beautiful stage continues the crossing of the equally magnificent French Vexin Regional Nature Park, heading generally eastwards. It joins andthen climbs up the Aubette de Magny valley, crosses a series of agricultural plateaus between Oise and Val d'Oise before descending into the Viosne valley to reach Chars.

A hike from station to station which, with a few climbs, leads from the Seine valley to the Oise valley. After the streets, alleys and paths of Triel-sur-Seine and Chanteloup-les-Vignes, you cross the Hautil Forest in a very pleasant way. Three beautiful churches and two beautiful farmhouses are to be discovered along the way.

Crossed by numerous waterways, the town of Chaumont-en-Vexin has been awarded the Petite Cité de Caractère label. Along the route, you can discover the rolling landscapes of the Vexin and the Troesne valley, with two megaliths along the way: the Dolmen des Trois-Pierres in Trie-Château and the Pierre Droite de Delincourt.

A hike starting from Valmondois towards the Château d'Ogivaux and the Moulin le Roy, then heading towards L'Isle-Adam through the woods. Walk along the left bank towards the new port of L'Isle-Adam, then around the lake, and continue along the banks of the Oise via the GR®1 greenway.

Half of the route takes you through the Forest of L'Isle-Adam. This hike from station to station offers other points of interest, including two covered walkways dating from the Neolithic period.

A station-to-station walk, which can also be done as a slightly shorter loop. The route is mainly woodland, using both signposted paths and little-travelled paths in the undergrowth. The Étang du Corra, a protected site, offers an interlude with beautiful views and the chance to spot many birds.
