Église Saint-Clair (Herbeville) walks

A fairly easy walk from station to station, the first part of which is through woodland where you can admire superb specimens of various species of deciduous trees, particularly beeches and oaks, which are certainly over a hundred years old. You also pass close to the Alluets-le-Roi telecommunications centre and its many antennas of all types.The second part, which is more varied, includes a visit to the ruins of Abbecourt Abbey and the centres of the villages of Orgeval and Villennes-sur-Seine with their churches. The walk ends with a pleasant stroll along the banks of the Seine.

On this walk from station to station, you’ll follow the Mauldre river through the countryside, passing through several villages to discover some heritage sights.

A walk on the plateaus above the Mauldre valley. A rolling landscape as far as the eye can see accompanies you throughout the hike.

From the Mauldre Valley to the Seine Valley, a hike from station to station that alternates between fields and woodland. The Étang d’Abbecourt offers a perfect spot for a break, and the Church of Saint-Étienne in Vernouillet adds a touch of heritage.

The walk begins with a very varied section of the GRP® "la Seine impressionniste", starting with the imposing ESA Ariane rocket factory and its loading dock, a charming marina, the Île de loisir du Val de Seine, and several very large ponds. It continues through Triel-sur-Seine, with its pleasant Parc Senet and the architecturally intricate St Martin’s Church. The walk through the Bois d’Hautil along easy yet unspoilt paths is well worth the detour for its chestnut forests dotted with a few fine oaks, and punctuated by a large number of sinkholes resulting from the collapse of underground quarries. And we finish off gently, admiring the confluence of the Oise and the Seine. ⚠️ User comment on 18 May 2026:>Please note: at point 8, the path is closed in both directions due to reported risks of collapse; instead, take the GR®2 further down to cross from east to west

Fourth stage of the Grand Tour de l'Île-de-France on the GR® 11 and start of the clockwise circular section.This stage takes place entirely in the Yvelines department, connecting Villiers-Neauphle-Pontchartrain station to Orgerus-Béhoust station, crossing the Beynes forest and the agricultural landscapes of the Yvelines. The route runs alongside the Avre aqueduct, which supplies drinking water to western Paris.

This stage is the last of the old GR®1 route. The departure point is at Villiers-Saint-Frédéric, at the RER station. The entire route is rural. It passes through several villages, including Saint-Germain-la-Grange, Thiverval-Grignon and Davron. There are two notable churches: those of Davron and Thiverval-Grignon, not to mention Feucherolles. This is an undemanding section that allows you to finish the GR®1 at a leisurely pace.

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 long hike from station to station that veers away from the Seine Valley (which is not particularly suitable for hiking in this area) and climbs to higher ground. The route alternates between wooded sections and stretches through fields with sweeping views. There is a wealth of heritage to discover, with two beautiful Romanesque churches in the first part and, towards the end and as a grand finale, the Gothic Collegiate Church of Mantes-la-Jolie.
