La Sygrie walks

This second section, dedicated to the Bièvre, begins in a still rural setting but quickly moves into a heavily urbanised area. However, the route favours small streets and public parks. It is also here that the river’s course becomes partly underground, reappearing here and there. There are heritage sites, notably the impressive aqueducts at Arcueil and Cachan, and beautiful views of Paris in the ‘upper’ part of the route.

From the Parc de la Vallée aux Loups to the Chateaubriand Museum and the botanical garden, via the Fontaine Levron, then the Parc Départemental de la Roseraie. A walk through the Parc du Domaine de Sceaux, along the grand canal, past the Octogone and, finally, past the 17th-century Château de Sceaux.

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.

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.

After enjoying the sweeping views from the Observatory Terrace, we wind our way through the many paths of Meudon. The Longs Réages cemetery holds a surprise in the form of a Neolithic dolmen converted into a modern burial site... This route ends along the Seine and on Île Seguin, where a concert hall complex with an apt name has now been built.

A hike from station to station in the southern part of the Meudon Forest. The route alternates between wide paths and little-used trails where a good sense of direction is required. Along the way, you will pass four pleasant ponds and come across a small Neolithic menhir.

An urban route that runs partly through public parks or woods, away from traffic! Each park has its own identity, and the town centres of Châtillon and Clamart add their own heritage touch.

Although densely urbanised, the Hauts-de-Seine department offers wonderful opportunities for walkers, with a rich heritage and often a little elevation. This series of hikes, almost all of which are accessible by public transport, takes you on a journey of discovery through this department, avoiding major roads as much as possible and favouring footpaths and alleys, public parks and wooded areas.

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.

A hike from station to station, mainly through forest. Although located in an urban setting, this route takes you through green (in season) and peaceful areas. The Chêne des Missions oak tree and the Étang du Trou au Gants pond are two beautiful points of interest.
