Allée couverte de Blanc Val walks

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 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.

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.

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.

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.

This route across Deuil-la-Barre from south to north connects Place de la Nation in the renovated Galathée district to Place de l'Église in the historic town centre. It takes about 40 minutes at a leisurely pace.This pleasant walk through numerous public gardens takes you to Place de l'Église (or Place de Victimes du V2), which is also the starting point for several hikes on the Côte de Deuil trails.This route is recommended by the association Les Sentiers de la Côte de Deuil.

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.

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.

An itinerary almost entirely surrounded by greenery in a densely urbanised area! The circular paths within the park are complemented by a walk along the banks of the Seine. The charming Jardin Ombre et Lumière (Shadow and Light Garden) and the reed beds of the lake are sure to delight enthusiasts.
