Église Saint-Pierre-ès-Liens (Bouray-sur-Juine) 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.

A walk from station to station that starts gently along the Essonne. Further on, the crossing of the Itteville marshes allows you to discover ponds and reed beds and admire the birds from the observation points provided. After passing an imposing menhir, you climb the Butte d’Itteville. You then reach the rocky outcrops of Le Sanglier. The walk ends with a stroll through the narrow streets of La Ferté-Alais.

From the Essonne Valley to the Juine Valley through woods and fields, passing by the Pierre Levée in Janville-sur-Juine and the Chamarande viewpoint. A route almost entirely on paths with beautiful views in the Gâtinais Français Regional Nature Park.

Twenty-ninth stage of the Grand Tour of Île-de-France via the GR®11, linking Ballancourt-sur-Essonne to La Ferté-Alais. Although both towns are located in the Essonne valley, the proposed route passes through the plateau overlooking the valley on the east side, in the Gâtinais Français Regional Nature Park, to the charming village of Mondeville. The GR® then winds its way between valleys, forests dotted with sandstone boulders and agricultural plateaus. This stage is shorter than the previous ones but is not without its difficulties as it still covers steep sections of terrain similar to the Fontainebleau forest, particularly around Mondeville. The route also allows you to discover some unusual sights, such as the Roches du Père La Musique in Ballancourt.

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.

This hike is certainly the most "aquatic" of those that can be undertaken along the Essonne. Indeed, numerous ponds punctuate the route: ponds for fishing or other forms of leisure; ponds and marshes that make up a protected natural area, a source of biodiversity and a place to observe wildlife.

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.

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.
