Orsay walks

Discover part of the artistic, historical and scientific heritage of Paris-Saclay University: sculptures, frescoes, scientific instruments, archaeological sites, and more. An easy walk on a campus featuring a large botanical park and the neighbouring wooded hillsides.

Discover nature between the River Yvette and the Guyonnerie forest. A family walk where pets are welcome.

A short hike that combines urban passages, wooded and hilly trails, and a pleasant walk along the Yvette River.

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.

A loop in the Chevreuse Valley, with magnificent landscapes, in a wooded and rural setting close to Paris. The first part is a walk through the woods on the plateau overlooking the Yvette Valley. The return journey, parallel to the outward route, is mainly on flat ground. Most of the walk is well shaded and flat, but there are also some fairly steep ascents and descents. The area is very popular with walkers and mountain bikers, but it is well worth a visit.

A walk of many faces! On forest tracks interspersed with paths through the city, you follow an old railway line with a tunnel and viaduct, finishing along the course of the river Yvette. A walk to enjoy at any time of year.

In a highly urbanised environment, this is a green space where you can relax and enjoy a pleasant walk along the Yvette river and the Bassins de Saulx and Balizy. A hike from station to station with a shorter alternative for motorists.

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.

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 hike starts in Gif-sur-Yvette and takes you to the heights of the Saint-Aubin and Vallée Bonnard channels, following the Yvette river and returning via La Mérantaise, passing through the Bois d'Aigrefoin, the Saint-Aubin communal forest and the Coupières basin.

Circular route through the Saclay plateau, the woods at the edge of the plateau and the Bonnard Marsh.

Hike in the Yvette Valley offering beautiful views of the plain with its market gardens and requiring some effort thanks to the steep wooded hillsides covered in particular by the Rocher de Saulx national forest.

This is a fairly short hike that allows you to discover two rigoles (small water collection channels) on the Saclay Plateau: the Rigole Domaniale and the Rigole de Favreuse. These rigoles were built in the 17th century to supply water to the Palace of Versailles. The route alternates between woods and cultivated fields, with a rich heritage in Vauhallan.

A varied route around Nozay, a charming village located twenty-four kilometres south-west of Paris. This hike takes you through diverse landscapes: fields, forests, and an equestrian centre. The topography is varied (flat expanses, hilly areas). Beautiful views of the village of Marcoussis.

Hike connecting Igny (Essonne) to the Palace of Versailles. The route follows the Bievre, and 80% of the route is on roads through forests. A calm, cool walk with scenery that will leave you with a unique souvenir.
