Église Saint-Martin (Thiverval-Grignon) 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 station-to-station walk, which can also be done as a slightly shorter loop. The route is mainly woodland, using both signposted paths and little-travelled paths in the undergrowth. The Étang du Corra, a protected site, offers an interlude with beautiful views and the chance to spot many birds.

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 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 will take you through the forest of the Haute Vallée de Chevreuse Regional Nature Park. Ponds, castle, forest, ramparts and museum: everything you need for a wonderful day out with family or friends.
