Carrefour de la Porte Baillet 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.

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.

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.

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.
