Roche Grenolée walks

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.

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 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.

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.

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.

On the edge of the Ile-de-France region, this hike from station to station follows the Essonne Valley from south to north. It takes forest paths, quiet minor roads and paths between fields. This route allows you to discover an interesting heritage: mills, churches and castles, as well as a menhir and a polisher that attest to the ancient human occupation of the area.

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.

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 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.
