Château de Chaumontel walks

Starting mainly in the forest and then crossing fields on good paths, this hike from station to station has its share of remarkable sights. You can enjoy an old market hall, two beautiful churches, a dovecote, a spring and a menhir, as well as a natural curiosity, the two intertwined trees in the Forest of Coye.

Visit Royaumont Abbey via Viarmes and Luzarches, following the GR®655 circular route, for a wonderful day out with the family.

Eleventh stage of the Grand Tour of Île-de-France via the GR®11, connecting Chantilly-Gouvieux station to the village of Borest, reached by crossing the Chantilly estate, the Chantilly and Ermenonville forests, with a detour through the historic centre of Senlis and, optionally, a moment of reflection in front of the memorial to the victims of the March 1974 plane crash. The route follows, more or less closely, the Nonette River, which is crossed several times. The route for this stage is almost entirely in the forest, with little elevation gain, making it a very pleasant hike, and the crossings of Chantilly and Senlis add a rich touch of heritage. This stage requires an overnight stay to avoid laborious car manoeuvres. It is therefore the first of two consecutive stages, both entirely within the Oise department, between the Chantilly-Gouvieux and Crépy-en-Valois railway stations.

La randonnée se déroule d'abord à travers la Forêt de Carnelle, avec un passage à la superbe Allée couverte de la Pierre Turquaise, la plus imposante d'Ile-de-France. On continue en forêt puis à travers champs, pas loin de l'Oise, pour une visite à l'ancienne Abbaye de Royaumont. On termine entre bois, prés, champs et zones résidentielles.

A circular loop from station to station accessible via line H. Starting from the town of Bouffémont, it takes you into the Montmorency Forest and on to the Château de la Chasse and its pond. Before and after the château, the route follows various forest trails in the shade of century-old trees.

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 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.

Tenth stage of the Grand Tour of Île-de-France via the GR®11, connecting the Cires-lès-Mello railway station to the Chantilly-Gouvieux railway station, around the River Oise and two of its tributaries, the Thérain and the Nonette. The built heritage here is remarkable, between the abbey church of Saint-Leu d'Esserent and, of course, the town and estate of Chantilly.

A hike through the forest, ideal for summer, passing through Saint-Leu, Montlignon, Montmorency, Saint-Brice-sous-Forêt and, finally, Écouen. A great way to spend a beautiful day with friends or family, and why not stop at a good restaurant in Piscop before finishing the route? 17/02/2026: Change of route between (11) and (12) to avoid a closed street.

The ninth stage, entirely in the Oise department, of the Grand Tour of Île-de-France on the GR®11, between the stations of Bornel-Belle-Église in the Esches Valley and Cires-lès-Mello in the Thérain Valley. It consists of a crossing of the Pays de Thelle, from west to east, in the south of the department, and always through magnificent varied landscapes, between woods and fields.
