Carrefour de la Fortelle walks

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.

Twelfth stage of the Grand Tour of Île-de-France via the GR® 11, connecting the village of Borest to Crépy-en-Valois station, both in the Oise department. This long stage consists of crossing the Valois region to Crépy-en-Valois, mainly through agricultural plains and wooded areas.

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.

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.
