About
Trail Walking of 28 km to be discovered at Ile-de-France, Val-d'Oise, Cergy. This trail is proposed by tracegps.
Description
Situé à l'ouest de Paris , le massif de l'Hautil domine les vallées de l'Oise et de la Seine ainsi que les plaines du Vexin français. Son altitude atteint 191 mètres, ce qui en fait un des points culminants le plus haut d'Ile-de-France. Plutôt connu pour ces anciennes carrières de gypse qui ont une fâcheuse tendance à s'effondrer, le plateau de l'Hautil offre une véritable oasis de verdure et abrite bien plus que des chevreuils et des éperviers.
