Église Saint-Martin (Mondeville) walks

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.

A hike from station to station with a significant forest component. In addition to a viewpoint, Rocher Bizet offers views of its plateau landscapes, with heathland, ponds and outcropping rocks.

This is the twenty-eighth stage of the Grand Tour of Île-de-France via the GR®11, connecting Milly-la-Forêt to the Ballancourt-sur-Essonne train station after crossing the French Gâtinais region. It is designed to follow on fromthe previous stage coming from Fontainebleau, after a night's stay there.This stage begins in the École valley, which boasts a rich heritage: Milly-la-Forêt, Moigny-sur-École, Courances and its château, and Dannemois, dear to Claude François. It continues through the fields of the Gâtinais, then the ridges and sandstone plateaus of the Grands Avaux forest, ending at Ballancourt-sur-Essonne in the valley of the same name.The stage is very beautiful but very long, and undoubtedly the most physically demanding of all those on the GR®11, especially in its second part. However, it is possible to split it in two by staying overnight and/or shorten it in several places by simplifying it.

A hike from station to station in the Essonne Valley. After climbing up through the Bois de Saint-Médard and crossing a cultivated plateau, you pass through the charming hamlets of Courdimanche. You walk alongside the river several times, cross a small island, and the Marais de Jarcy may be of interest to nature lovers. Several churches and a few wash houses are also along the way.

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 long hike takes you on a fairly comprehensive tour of the magnificent Coquibus massif: heather-covered plateaus and water holes, deciduous woods, rocks, viewpoints, the Vanne aqueduct (sandstone steps), etc.

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.

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.

After crossing the Rambouillet Forest in the previous stage, this section is a restful one. It takes you to Malesherbes station. This is one of the easiest stages of the GR®1. The start is at Le Vaudoué. It is the only stage of the GR®1 that does not start at a station. The hike alternates between sections in the woods and more rural sections. The first interesting sight on the route is the church in Le Vaudoué. The path then leads to the former Templar Commandery before crossing woods and fields towards the Essonne and Saint-Martin Church in Malesherbes.

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.
