Menhir du Pierre-Beaumirault walks

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.

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 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.

A hike from station to station that constitutes the last stage of this route along the Orge River, ending at its confluence with the Seine. Although the area is highly urbanised, the walkway along the river, which takes us back and forth across it, often offers a bucolic setting.

This route is the second of four sections of the Charles Péguy Trail: Lozère (Palaiseau) - Chartres via Dourdan. It follows in the footsteps of the poet Charles Péguy, who celebrated his two pilgrimages (made in 1912 and 1913, each lasting four days there and back) in a poem that remains famous to this day. This is the transition stage: from the valleys and rolling hills of Hurepoix to the Beauce plateau.

A varied hike where you gain altitude. First, you climb up to the Saclay plateau and walk along the university campus before gently descending into the Yvette valley through the forest. We climb back up the other bank and cross the Gif-sur-Yvette forest from east to west. After an urban section, we walk between fields before descending back into the forest to Saint-Rémy-lès-Chevreuse.

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.

This marked route follows as closely as possible the path taken by Charles Péguy in 1912 and then 1913 from his home in Lozère (Palaiseau) to Chartres, via Dourdan. The walking route is 94 kilometres long and is marked with blue and white signposts. The trail was created by the Amitié Charles Péguy association. It received support from the Eure-et-Loir General Council. Visorando was responsible for its first publication on the Internet.

First of the four sections of the Charles Péguy Trail: Palaiseau-Chartres, via Dourdan. It closely follows in the footsteps of the poet Charles Péguy, who made two pilgrimages in 1912 and 1913, each lasting four days there and back.
