Les Granges-le-Roi walks

40 km from Paris, an unexpected valley. It marks the transition from the Beauceron plateau to the Paris Basin: this is the Hurepoix.

This stage is the last of the GR®1 and is over 30 km long. It crosses the western part of the Rambouillet Forest. The entire stage is through forest, except for the crossing of Saint-Léger-en-Yvelines. The route connects two towns with a rich history: Dourdan and Rambouillet. There are many straight lines on this route, which is mainly flat. There are a few notable ponds at the end of the route, such as the Étang de la Tour and the Étang d'Or.

On the border between Hurepoix and Beauce, this circular route alternates between paths through fields and woodland. Along the way, you will pass two villages with old churches and beautiful houses.

A lovely woodland walk with a cultural touch.

A hike from station to station in the upper Orge valley, following the river. Discover the rich heritage of Dourdan town centre (fortified castle, 12th-13th century church, wash houses, etc.) as well as beautiful churches along the way.

The Orge river flows through the Essonne department, first from west to east and then diagonally from south-west to north-east. This route follows the valley as closely as possible, where it is accessible by train. The route alternates between paths along the river, including a promenade in the downstream section, passages through the undergrowth, residential areas and urban routes.

A hike from station to station, crossing the Dourdan Forest, the Bois de Saint-Benoît, the Bois de Pinceloup and the southern part of the Rambouillet Forest. Several lakes adorn the route and the church of Saint-Arnoult-en-Yvelines adds a superb touch of heritage.

Discover Dourdan and its national forest.

A short route to discover the village and the surrounding countryside, for nature lovers. Along the way, there are several beautiful viewpoints along the Orge river and a final stop at the Chateaupers farm.

An easy walk to discover ponds, a beautiful lightning-struck tree and a beautiful viewpoint, all in the Dourdan National Forest, so the route is well shaded. The ground may be muddy in places in wet weather.

The undergrowth is dotted with flowers in March and April and there are remarkable trees all along the route.

A long walk through forests, ponds and the banks of the Orge river, passing through the beautiful villages of Sainte-Mesme and Saint-Martin de Bréthancourt. Includes a visit to Dourdan, which you cross via parks and walking trails along the Orge river or the old fortifications, avoiding the suburbs and their buildings.

From Sermaise to Roinville via the GR®1 on the southern slope of the Orge, through woods and fields and a few hamlets, then back to Sermaise via the northern slope, to the edge of the Bois du Marais.

The first part of the route follows the upper reaches of the Orge river in a very bucolic setting. The second part is on a cultivated plateau with extensive views. The end of the route is in the forest, with beautiful trees here and there.

A short half-day hike in the forest, with several ponds along the way.
