Gare d'Osny walks

A hike from station to station with the Oise as the guiding thread. You will cross several wooded parks and follow the river for a long time, mostly on a right of way. At the end of the route, the passage through Auvers-sur-Oise is an opportunity to evoke the famous painter Vincent Van Gogh.

A lovely, flat route to enjoy at your leisure along the banks of the Oise, with a high point at the back of the Pays de Maurecourt offering magnificent views of the Oise. This region is even more beautiful when seen from the footpaths.

A station-to-station walk, which can also be done as a slightly shorter loop. The route is mainly woodland, using both signposted paths and little-travelled paths in the undergrowth. The Étang du Corra, a protected site, offers an interlude with beautiful views and the chance to spot many birds.

A hike from station to station which, with a few climbs, leads from the Seine valley to the Oise valley. After the streets, alleys and paths of Triel-sur-Seine and Chanteloup-les-Vignes, you cross the Hautil Forest in a very pleasant way. Three beautiful churches and two beautiful farmhouses are to be discovered along the way.

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.

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 lovely walk along the banks of the Seine, passing through pretty villages such as Evecquemont. The starting point and finishing point are two stations on the same SNCF line.

A hike from station to station that crosses the entire western part of the Saint-Germain-en-Laye National Forest. A few ancient crosses mark this forest trail. The route ends in Poissy, where you can admire the Notre-Dame Collegiate Church.

A hike from station to station that crosses the entire eastern part of the Saint-Germain-en-Laye National Forest. A few crosses and oratories mark this forest trail. The route ends in Saint-Germain-en-Laye, where you can admire its castle, built in the 12th century.

The walk begins with a very varied section of the GRP® "Impressionist Seine" trail, starting with the imposing ESA Ariane rocket factory and its loading dock, a charming marina, the Val de Seine leisure island, and several large ponds. It continues with Triel-sur-Seine, its pleasant Parc Senet, and its Église St-Martin with its complex architecture. The crossing of the Bois d'Hautil via easy but unspoilt paths is worth the detour for its chestnut forests dotted with a few beautiful oak trees and pierced by a large number of chasms resulting from the collapse of underground quarries. The walk ends peacefully as you admire the confluence of the Oise and the Seine.
