Coquibus Arcades (Sensitive biological reserve)
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.

This sector, mainly exposed to the North but quick-drying in its upper part, gathers 50 problems, most opened by Frédéric Buc. Access: on the road from Courances to Arbonne, park the car at the aqueduct. Follow the underground part of that one by a path, up to the stairs of Montrouget. Go around the hill by the right (white marks) and arrive at Le Chemin de la Roche qui Tourne near Le Carrefour des Fauves. The boulders are on the East of that crossing, all in the plot 7, except Sinus-X which is located in the plot 6.
