Bassin de Saint-Michel 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.

A hike from station to station, mostly following the Orge river or its secondary branch, the Grande Boële, and along a few large reservoirs. There is a rich heritage to discover, in Arpajon at the start of the hike and, as a highlight, at the Basilica of Longpont.

A hike from station to station, along the Orge and its tributary, the Rémarde, as well as the Bassin de Trêvois. A small menhir and a Louis XIII-style castle add a nice touch of heritage.

A hike from station to station that alternates between urban and forest passages. From the Yvette valley, we climb up to the Saclay plateau, where the university campus is constantly expanding. At the start of the descent, we visit an old sandstone quarry that has been converted into a climbing school.

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.

This hike follows the route of the T12 tram-train, connecting Massy-Palaiseau to Évry-Courcouronnes, and allows you to discover a varied landscape combining urban areas, natural spaces and neighbourhoods undergoing rapid change. The route takes you along the greenway that runs alongside the T12, between Épinay-sur-Orge station and the Évry-Courcouronnes terminus, offering a pleasant and safe section for pedestrians and cyclists. This walk offers an immersion in the areas served by this new line, with opportunities to stop at the various stations to fully enjoy the local heritage and green spaces.

Second stage of the Grand Tour of Île-de-France via the GR®11, from Massy to Saint-Cyr l'École, behind Versailles.This stage, more bucolic than the previous one, consists of continuing up the Bièvre river in its valley, where it is almost entirely in the open air. Arriving near its source in Guyancourt, the GR® leaves the valley and continues towards Saint-Cyr-l'École.

A varied hike where you gain altitude. First, you climb up to the Saclay plateau and walk along the university campus before gently descending into the Yvette valley through the forest. We climb back up the other bank and cross the Gif-sur-Yvette forest from east to west. After an urban section, we walk between fields before descending back into the forest to Saint-Rémy-lès-Chevreuse.

Twenty-ninth stage of the Grand Tour of Île-de-France via the GR®11, linking Ballancourt-sur-Essonne to La Ferté-Alais. Although both towns are located in the Essonne valley, the proposed route passes through the plateau overlooking the valley on the east side, in the Gâtinais Français Regional Nature Park, to the charming village of Mondeville. The GR® then winds its way between valleys, forests dotted with sandstone boulders and agricultural plateaus. This stage is shorter than the previous ones but is not without its difficulties as it still covers steep sections of terrain similar to the Fontainebleau forest, particularly around Mondeville. The route also allows you to discover some unusual sights, such as the Roches du Père La Musique in Ballancourt.
