About
Trail Walking of 22 km to be discovered at Ile-de-France, Yvelines, Magny-les-Hameaux. This trail is proposed by tracegps.
Description
Au départ de la Croix du Bois à Voisins le Bretonneux, l’itinéraire franchit la vallée de la Mérantaise pour rejoindre la vallée du Rhodon où il retrouvera Port Royal des Champs et le chemin de Jean Racine. L’étang des Noës est un motif pour prolonger la boucle vers l’ouest, avant de retrouver la forêt domaniale de Port Royal. Après avoir longé le circuit automobile Beltoise de Trappes, il contourne les étangs du Manet, puis revient à Voisins le Bretonneux en versant nord du vallon de la Mérantaise.
