Avoid leaving the paths and keep your dog on a leash from April to July.

Coquibus is an extremely sensitive area for several reasons and it must be protected. To do this, it is imperative to climb while limiting the impact on the environment as much as possible (brushing, magnesia, trampling the ground) in addition to the general recommendations on our ethics page.
This small area gathers a few problems, most of them difficult, to the West of the classical sector of Montrouget. It is located in a sensible zone : please limit the use of magnesium and don't make marks on the boulders.
Access: on the road from Courances to Arbonne, park the car at the aqueduct. Follow the underground part of that one by a path and pass a fence. For the aqueduct sector, climb the stairs to the top : the boulder are underneath, on the East of the hill. For the El Dorado sector, take the Chemin des Arcades to the left at the foot of the slope, join the Chemin de la Roche qui Tourne under the Arcades and go up the slope to the left a little after the end of these.
