Château de Gillevoisin walks

This stage of the GR®1 is one of the most difficult on this GR®. It is 32 km long and has an elevation gain of over 400 m. It is also one of the most beautiful. Starting from Lardy, this hike takes you past magnificent monuments such as the Church of Saint-Sulpice, the Church of Saint-Yon, the Church of Sermaise and the Château de Dourdan. There are other monuments to visit in this town. Most of the route is in the countryside, with several ascents and descents into the valleys. The route passes through numerous villages of varying sizes.

This walk, which takes place mainly on tarmac roads, forms a transitional stage in this journey along the Juine. Passing through a few pretty villages, two old mills, a beautiful church and a geological curiosity add to the charm of this route.

A hilly route from station to station, mainly through farmland for the first two-thirds, then through more wooded areas. Beautiful churches and rural heritage can be found in the villages along the way. In Dourdan, the walk along the Orge river, the 12th-13th century church and the fortified castle provide a superb finishing touch.

Thirty-first stage of the Grand Tour of Île-de-France via the GR®11, linking Étréchy in the Juine Valley to Saint-Chéron in the Orge Valley, via the Renarde Valley. It winds its way through the Hurepoix and the southern edge of the Beauce, offering varied landscapes, from plateaus to valleys and fields to forests. It is notable for its numerous ascents and descents between plateaus and valleys.

This walk from station to station leaves the Juine valley and climbs higher. After leaving the small town of Étréchy, the first part of the walk takes place mainly amongst cultivated fields. From the village of Mauchamps, the route becomes more varied and runs partly through woodland. There are several beautiful churches to see in Étréchy, Mauchamps and Torfou, not to mention the superb church of Saint-Sulpice-de-Favières, for which a detour is suggested.

The main aim of this walk is to reach La Roche Turpin from a station (RER C). La Roche Turpin is a magnificent natural area consisting of a sandstone plateau and its slopes, covered by a beautiful forest mainly populated by oaks (including some superb specimens), chestnut trees and Scots pines.At the start, you can enjoy the path around the Bassin de Trévoix (Retenue de l'Orge). You then make a pleasant walk through the village of Bruyères-le-Châtel via a dense network of well-maintained footpaths. Next comes the beautiful forest of Bruyères-le-Châtel (although there are long straight stretches due to fences enclosing large areas).

A hike from station to station, mostly following the Orge river or its secondary branch, the Grande Boële, and along a few large reservoirs. There is a rich heritage to discover, in Arpajon at the start of the hike and, as a highlight, at the Basilica of Longpont.

A hike from station to station, along the Orge and its tributary, the Rémarde, as well as the Bassin de Trêvois. A small menhir and a Louis XIII-style castle add a nice touch of heritage.

A varied walk, from station to station. After the footpaths and the church at Cerny, the route becomes predominantly woodland. It winds through the Bois Charron and climbs up the hill of La Roche Cornue, dotted with boulders. After a pleasant walk through the Bois de Miséry, you return to the Essonne valley and its villages.

Thirtieth stage of the Grand Tour of Île-de-France via the GR®11, linking La Ferté-Alais, in the Essonne valley, to Étréchy, in the Juine valley, through the western part of the Gâtinais Français Regional Nature Park. It consists of continuing the crossing of the Essonne, between agricultural landscapes, small forest ranges and more imposing valleys. A relatively short stage without any major difficulties, before the next two, which will be a little longer.
