Carrefour du Dauphin 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.

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 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.

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

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.

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.

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.
