Dominant Nyons, the mountain of Garde-Grosse (944 m) presents a puzzle of coniferous and leafy rejoicing the eye in any season. Rather than ascending it, we will walk along the small tracks that encircle it, like its rivers. Departure from Nyons via Chemin du Crapon to go up the Eygues to Les Pilles and around Essaillon which forms the extension of Garde Grosse towards the east. We will then proceed to the valley which separates, to the south, the mounts of Autuche, and to the north Essaillon then Garde-Grosse. It is by going up La Bordette, nice stream, with the national forest of the Coucou to the north, that we reach Chateauneuf-de-Bordette and then cross the Col de La Croix. During the descent, we follow the Rieu Before the district of Blaches at the west flank of the mountain. Between wild and the more domestic parts, Garde-Grosse and Essaillon shows its diversity even if the emblematic olive tree of Pays de Nyons plays a major role.
