Large stretches of sand, a pine forest, climbing rocks, and beautiful viewpoints, make the 25 Bosses one of the most original hikes in Ile-de-France. With a cumulative difference in height estimated at 800 meters, this trail is used in particular by local hikers wishing to train before a more serious hike in the Alps.
A must see in the 3 Pignons massif.

Clairement une des balades le plus exigeantes d’Île-de-France, de par sa longueur et son dénivelé ! Très agréable en raison des pins et des chaos rocheux, typiques de la forêt de Fontainebleau.
J’ai croisé plus de coureurs que de marcheurs.
