Coquibus is a particular and very sensitive part of the forest which must be treated with the greatest respect by visitors. Its status as a biological reserve allows you to climb there but this could one day be called into question due to too many visitors or irresponsible behavior. We ask climbers to limit their presence or otherwise their impact in the different areas of Coquibus as much as possible. In particular, do not go in groups, do not climb after sunset and do not use electrical devices (drones, fans, radios, etc.). Reduce chalk to the strict minimum, erase all traces of your passage and finally do not brush new boulders. Avoid leaving the paths and keep your dog on a leash from April to July.

Please read 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.
