Ancienne Batterie de la Châtaigneraie walks

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.

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.

Greenery and culture abound on this hike from station to station (RER B) between Antony Croix-de-Berny and Sceaux. It passes through a veritable breeding ground for Nobel Prize winners. It takes in splendid parks, including Parc de Sceaux, Arboretum de Chatenay-Malabry, Vallée aux Loups and Parc Henri Sellier. It allows you to discover the places where no fewer than six Nobel Prize winners lived: Marie Curie, physics then chemistry, and Pierre Curie, physics with his wife, Frédéric and Irène Joliot-Curie, together for chemistry, Sully Prudhomme, literature, and Luc Montagnier, medicine.

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.

A varied hike starting from Parc de Sceaux, passing through Parc de la Vallée aux Loups, the house of Chateaubriand, the garden cities of Plessis-Robinson with its allotments and river, which runs at the foot of the buildings. The hike ends with a walk through the forest of Meudon.

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.

This hike crosses Parc de Sceaux and the Verrières National Forest, then continues along the Bièvre, whose valley has been developed with numerous sports and leisure facilities. The presence of so many green spaces is surprising in an otherwise highly urbanised region.

A short hike on the slopes of the Val de Seine, through the old Fort d'Issy, which has been redeveloped, the public gardens of Issy-les-Moulineaux and the paths and stairs of Meudon. An urban route with some elevation changes, offering beautiful views and a diverse heritage.

After following paths through the town, this walk from station to station offers the chance to discover the Meudon Observatory and admire the sweeping views from the terrace of its park. The rest of the route is mainly through forest.
