Église Notre-Dame de l'Assomption (Le Coudray-Montceaux) walks

This is an unusual route, as the outward journey is by train from Montgeron station to Combs la Ville-Quincy-sous-Sénart station, and the return journey is on foot along a path that largely follows the banks of the Yerres.

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 pleasant walk along two rivers, the Yerres and the Réveillon. You completely forget the nearby urban environment.

A hike from station to station in a semi-urban environment, following paths through gardens and pleasant riverside trails.

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.

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 stage of the GR®1 connects Bois-le-Roi to Le Vaudoué. It is the only stage that does not end at a train station. This hike is unique in that it crosses the Forest of Fontainebleau and its many beautiful rocks. There are several points of interest along this section, which is entirely forested: the tree at Carrefour des Longues Vallées, the rocks at Cuvier Chatillon, the viewpoint at Gorges d'Apremont and Gorges de Franchard (worth visiting if you don't mind walking a little further), as well as the Chapel of Prieuré Notre-Dame de Franchard and the church at Vaudoué.

From Bois-le-Roi to Fontainebleau, walk between forest and rocks far from the beaten track

The Fontainebleau Forest is one of the most beautiful forests in France thanks to its varied landscapes and, above all, its sandstone blocks. This hike, which passes through the Cuvier-Châtillon rocks, the Apremont gorges and the rocks of Mont Ussy, will allow you to appreciate all its beauty but also its fragility, due to both natural erosion and that caused by heavy human traffic, given its proximity to the Paris region.

A hike from station to station, the first half of which takes place entirely in the northern part of the Forest of Fontainebleau, with a passage through the rocky chaos of Rocher Canon and then to the mysterious Mare aux Évées. The route then becomes much more urban, passing through several residential areas. It finally ends on the Seine towpath.
