A very pleasant walk that begins along the surrounding wall of a castle beautifully set in its grounds. The walk takes you through the hamlet of Héréville with its beautiful houses and charming tranquillity. Although the route ends on a road, it is very quiet and the narrowness of the road forces cars to drive at a speed that makes them very tolerable.

This area is classified as a natural zone of ecological, faunistic and floristic interest (ZNIEFF).

A circular route between plains and woods, around Auvers-sur-Oise.

This hike passes through the villages of Auvers-sur-Oise, Valmondois and Butry-sur-Oise, alternating between countryside and the banks of the Oise. All these places have provided numerous subjects for landscape painters, notably Dupré, Daubigny and Pissarro, precursors of the Impressionists. Even today, visitors are struck by the charm of this region in all seasons.

This hike is a shorter version of the hike called "The Isle-Adam National Forest and its southern edge". The route, with sections through the forest and paths across fields and meadows, offers beautiful woodland scenery and sweeping views of the surrounding countryside thanks to the gently rolling terrain.

The Chauvry Valley is a listed site, particularly due to its biological richness. It is bordered by the forest massifs of Isle-Adam to the north and Montmorency to the south and stretches from the Oise valley to the Plaine de France. The hike takes place in rolling agricultural and wooded landscapes and passes through the grounds of the Château de Méry-sur-Oise.

From Nerville-la-Forêt, take a short hike in the Forêt de l'Isles Adam with visits to three villages and three churches. This hike is popular in summer when it is hot thanks to the cool shade of the trees in this forest, and also in winter as the ground is not too muddy.

This route is rich in history and allows you to discover the heritage of Pontoise and its little-known paths.
