Etang des trois sources walks

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.

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.

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.

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.

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.

A hike from station to station in two stages. In the first stage, you stay at a higher elevation and enjoy beautiful views of the Seine and its valley. In the second stage, you stay closer to the river. The beautiful Saint-Martin Church in Herblay and the important river transport industry in Conflans-Sainte-Honorine add to the charm of this hike.

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.

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.

In the footsteps of the Impressionists, an urban route mostly along the banks of the Seine, through the Parc Départemental de l'Île Saint-Denis. At the end of the route, the Basilica of Saint-Denis adds a superb touch of heritage to this short walk.

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.
