Poissy walks

A former royal hunting ground, the forest of Saint-Germain-en-Laye now offers beautiful high forests with a variety of tree species. The proposed route, marked by old crosses and oratories, reflects this diversity.

A mainly forest route, alternating between wide paths and trails winding through the undergrowth. An opportunity to discover a charming pond and explore a well-maintained botanical trail.

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.

The first part of the circuit from Bures to Chapet passes through fields along farm tracks, then crosses Chapet and reaches the hamlet of Brezolles, before returning through the woods

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.

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.

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 beautiful hike through Le Vésinet, with its five lakes and rivers, as well as along the Seine.

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 is a very simple walk, as it follows the Seine almost from start to finish. There are beautiful views of the river and large, attractive houses along the way.

The route follows the Avenue Verte (Paris-London cycle route) from Jouy-le-Moutier to Vauréal. After crossing the Oise at the major axis, it returns via the Cergy ponds and the towpath to the Pont de Neuville bridge.

A short walk, where heritage sites (churches, wash houses, covered walkway) alternate with a path along the Oise river.

A short walk along the streams of the Plaine de Versailles, including the Ru de Gally, which rises in the castle grounds. The charming village of Rennemoulin boasts a chapel, a wash house and an old bridge, while the Fontaine de Maltoute is a pleasant place to stop and rest in the shade.

A mainly forest route with a pleasant section along the Etang de Saint-Cucufa and a brief detour through a residential area and old orchards to enjoy a beautiful view from the Belvédère des Gallicourts. A half-day walk.
