About
Trail Walking of 7.5 km to be discovered at Ile-de-France, Essonne, Buno-Bonnevaux. This trail is proposed by guydu41.
Description
Le circuit en sens horaire commence depuis un petit parking au Hameau de Chantambre, 8 Route de Malesherbes, 91720 Buno-Bonnevaux.
Dans la vallée boisée de Vautretion il chemine sur des sentiers étroits, tortueux, embroussaillés, longeant plusieurs chaos rocheux pour remonter sur le haut du côteau.
L’approche du mégalithe se fait par un chemin puis un sentier envahi par les ronces pour arriver en bordure d’un champ (sécateur fortement recommandé).
Sur le haut du plateau, il faut longer un champ ceinturé par une petite clôture électrique jusqu’au Polissoir de Grimery situé à la lisière du bois.
Remarque importante : Respectez la clôture, les surfaces cultivées et ne marchez pas dans le champ.
Reprendre le même chemin pour redescendre dans la vallée puis le quitter en empruntant des chemins larges et entretenus descendant vers la Grande Vallée puis vers la vallée de l'Essonne jusqu'à Chantambre.
