Église Saint-Jean-Baptiste (Leuville-sur-Orge) walks

A hike from station to station that constitutes the last stage of this route along the Orge River, ending at its confluence with the Seine. Although the area is highly urbanised, the walkway along the river, which takes us back and forth across it, often offers a bucolic setting.

The main aim of this walk is to reach La Roche Turpin from a station (RER C). La Roche Turpin is a magnificent natural area consisting of a sandstone plateau and its slopes, covered by a beautiful forest mainly populated by oaks (including some superb specimens), chestnut trees and Scots pines.At the start, you can enjoy the path around the Bassin de Trévoix (Retenue de l'Orge). You then make a pleasant walk through the village of Bruyères-le-Châtel via a dense network of well-maintained footpaths. Next comes the beautiful forest of Bruyères-le-Châtel (although there are long straight stretches due to fences enclosing large areas).

A short walk, urban at the start and finish, which, in between, combines a pleasant stroll along the River Yvette with wooded and undulating paths.

First of the four sections of the Charles Péguy Trail: Palaiseau-Chartres, via Dourdan. It closely follows in the footsteps of the poet Charles Péguy, who made two pilgrimages in 1912 and 1913, each lasting four days there and back.

This marked route follows as closely as possible the path taken by Charles Péguy in 1912 and then 1913 from his home in Lozère (Palaiseau) to Chartres, via Dourdan. The walking route is 94 kilometres long and is marked with blue and white signposts. The trail was created by the Amitié Charles Péguy association. It received support from the Eure-et-Loir General Council. Visorando was responsible for its first publication on the Internet.
