Abbaye de Port-Royal-des-Champs walks

The upstream part of this series of three hikes devoted to the Bièvre river. A very pleasant walk along the river and its bodies of water, in a mostly rural setting. A hike from station to station, which can be used to adjust the length depending on the weather conditions or desires of the hikers.

A hike from station to station that takes us to the source of the River Yvette and then up and down through the woods that frame its valley. The route crosses the Maincourt Marsh and then an area of rocky chaos. The forest trails are interspersed with villages and hamlets rich in heritage.

A hike from station to station with a water theme! In the Parc Naturel de la Haute Vallée de Chevreuse and then in the Forêt de Rambouillet, a pleasant route, mostly shaded, along ponds, small canals and a charming river, the Drouette.

A hike from station to station that takes you on a rollercoaster ride through the Fausses-Reposes Forest and Saint-Cloud Park. Along the way, you can enjoy the Étangs de Ville-d'Avray, the park's ponds and statues, and a superb view of the Val de Seine and Paris.

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.

Set off on a pleasant bike ride in the heart of the Hauts-de-Seine, combining contemporary art, greenery and local culture. This approximately 6-kilometre route connects the modernity of the Seine Musicale in Boulogne-Billancourt with the originality of the Playing Card Museum in Issy-les-Moulineaux, passing by the unusual Tour aux Figures on Île Saint-Germain.

This is a very simple walk, as it follows the Seine almost from start to finish. There are beautiful views of the river and large, attractive houses along the way.

A route through two wooded areas on either side of the Seine. From one large waterfall to another, from one racecourse to another, the hike alternates between paths and urban passages, flower beds and sculpted heritage, ponds and lakes.

A short hike that starts on a little-known path along the Seine. It then runs alongside the Longchamp racecourse and the Suresnes and Longchamp ponds. After a brief stop at the Grande Cascade, it reaches Lac Supérieur and explores its southern tip. The route ends with a crossing of the Auteuil racecourse, on days when there are no horse races, of course.

The route mainly follows the Seine towpath, close to the river, and should not be attempted during periods of high water. Many houseboats are permanently moored along the route, which ends at the foot of the impressive towers of La Défense. Do not undertake this trip when the Seine is in flood.
