A pleasant hike along the Sausseron, a small stream in Valmondois, past the mills and back via the steam tramway museum and its old railway line.

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

A very varied hike through green valleys, cultivated plateaus and forests. Some beautiful views of the surrounding countryside and the crossing of villages with interesting architectural heritage make it very enjoyable.

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.

The Croix des Friches dates from the Middle Ages and marked the boundary between the communes of Parmain and Nesles-la-Vallée. The beautiful Forêt de la Tour du Lay is home to a Neolithic polishing stone. A hike mainly through woodland, with a few sections between cultivated fields.

The circuit starts by taking you along the Sausseron valley, then climbs up the hillside and continues through fields. You return to Nesles via paths through the woods. The circuit also allows you to discover a unique site called the Trou à Morts.

A circular route through five villages in the Vexin Regional Park, partly following the old Valmondois Marines railway line, a secondary line that closed in the 1950s but whose old stations are still visible.

A peaceful walk, accessible to all and mostly shaded.

You will walk along both wide, straight paths designed by Le Nôtre, with star-shaped crossroads, and small paths that wind along the edge of the forest, with sections overlooking the Marais de Stors Nature Reserve and the large Abbaye du Val Park.

Hike in the Isle-Adam National Forest, passing through areas overlooking the Stors Marsh Nature Reserve and the large Abbaye du Val Park with its quarries, caves and Château des Forgets. The GPX track may be useful.

A circular route alternating between tarmac roads, dirt tracks and forest paths, which takes you around the Bois de la Tour du Lay from Champagne-sur-Oise and offers views of the Oise valley. Along the way, you will pass a Neolithic polishing stone. The Bois de la Tour du Lay is classified as a departmental forest and bears the name of an old parish. This area is classified as a natural zone of ecological, faunistic and floristic interest (ZNIEFF).
