L'Étang-la-Ville walks

A relatively short route but with some steep slopes, in a beautiful forest setting.

A mainly forest route with several remarkable trees here and there. The site of the Croix Saint-Michel offers a view stretching as far as Paris. A short but fairly challenging hike, given the alternating ascents and descents (the total elevation gain is probably underestimated; allow for around 200m).

A hike from station to station that crosses the Marly National Forest and then the Tailles d'Herbelay Departmental Forest. It then offers a visit to the charming town centre of Chambourcy and a short walk in the Saint-Germain-en-Laye National Forest. The route ends in Poissy, where you can admire the Collegiate Church of Notre-Dame and the remains of the Old Bridge over the Seine.

Around Saint-Nom-la-Bretèche station - Marly Forest, a walk in a beautiful deciduous forest. It suffered greatly from the great storm of 1999, which flattened the oak trees on the motorway like straw, but this hike has a high density of remarkable trees (oaks, hornbeams, beeches). As the Marly forest is crossed by several busy roads, this hike focuses on the quietest part. It also offers a few viewpoints.

This circular mainly covers the Marly Forest, allowing you to walk theGR®1from Chambourcy to Louveciennes. On the way back, the route crosses the Parc du Domaine Royal de Marly.

The park is located in Marly-le-Roi and managed by the Public Establishment of the Palace, Museum and National Estate of Versailles. A sloping park on the south bank of the Seine, its lower part overlooks the centre of Marly. To the east, it is very close to the Louveciennes national forest, from which it is separated by the Route de Versailles. It still features the grand alignments of the Louis XIV era, the layout of the château on the ground, and the drinking trough downstream of the park with its two basins topped by copies of the Chevaux de Marly. The royal gate and the gates of the former château, such as the main gate and the Phare gate, protect access to the estate. The GPX track may prove useful.

The route goes around the Joyenval golf course, on which the old abbey is located, and passes in front of the Désert de Retz. The ruins of the Château de Montjoie and a hunting table are also located near the route.

A half-day walk, mainly in the woods, with a beautiful pond and the vast lawn of the Domaine de Beauregard.

A former royal estate (Louis XIV liked to entertain his friends here, away from the court), the Parc de Marly combines a rich heritage with the pleasure of strolling along woodland paths, wide avenues and vast lawns.

This circuit consists almost exclusively of paved forest roads, at least in part, and is closed to motor traffic. This allows you to hike in the forest without having to surf on paths full of water and mud in winter.

The Forest of Marly covers 2,000 hectares about twenty kilometres west of Paris, between Saint-Germain-en-Laye and Versailles. It stretches 12 km from east to west and connects to the Forest of Saint-Germain-en-Laye via the Plaine de la Jonction. It is a former hunting ground of the kings of France. The hike includes a route through this forest starting from Bailly.

This short walk allows you to explore the surroundings of Bailly and Roquencourt. If the forest ground is muddy, you can return via the same route you took on the way there. Bailly and Rocquencourt are located in the Versailles plain on the edge of the Forest of Marly. The municipal area of Rocquencourt is relatively small: it is one of the smallest municipalities in the Yvelines department.

From station to station through the Forest of Saint-Germain-en-Laye with a short detour through the historic centre of the village of Mesnil-le-Roi. Arrival in Conflans-Sainte-Honorine, capital of inland waterway transport.

Starting from the Saint-Germain-en-Laye RER station, this loop begins on the grounds and terrace of the château, then alternates between wide forest paths and trails that wind through the undergrowth.

From boatmen to Henry IV, this walk reveals what lies beneath the terraces of the Château de St Germain: paths winding between the pavilions, trees from the Île-de-France region, a walk under the terrace, the banks of the Seine and Corbière Park.

A mainly forest route despite its proximity to Paris! After crossing the Bois de Louveciennes, you can enjoy the Parc de Marly, with its views and ponds. The route ends in the Marly National Forest, with a winding path at first, then a wide, straight path.

A hike from station to station that runs mainly along the Seine, mostly on well-marked footpaths.

A hike from station to station, crossing the southern part of the Saint-Germain-en-Laye national forest. The start and end of the route are in urban areas. In Poissy, the Collégiale Notre-Dame offers a superb touch of heritage.

The commune of Le Vésinet enjoys a unique status in France as it is a "park town". It was designed with rivers and lawns, and houses surrounded by huge gardens. Its proximity to the Seine makes for a varied and very pleasant walk, easily accessible by RER. At the end of the walk, the Île des Ibis offers a reward for young and old alike: a children's playground and numerous water birds to observe.

A short walk along the streams of the Plaine de Versailles, including the Ru de Gally, which has its source in the castle grounds. The charming village of Rennemoulin boasts a chapel, a wash house and an old bridge, while the Fontaine de Maltoute fountain offers a pleasant, shaded spot to stop for a break. Unacceptable behaviour has been observed; see the warning in the practical information section.

A pleasant hike through the forest and along a golf course in a little-known part of the Marly National Forest.
