Montrouget Est (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.
Please read our ethics page.
On the road from Courances to Arbonne, leave your car at the first parking to the right when entering the Bois du Coquibus. Take Le Chemin de la Ferme du Montrouget, turn left till the Chemin des Arcades, and continue on a small path to the South between Montrouget and point "97" on the IGN map, with Figure de Style. The main sector is 150m away (with an evident "big nose"), before reaching Le Chemin de la Roche qui Tourne.
Other access: from the next parking, take the Chemin des Côtes de de Courances (parcelle 37), cross the Chemin des Arcades (white markings), turn right on the GR 11 (Chemin de la Roche qui Tourne). The sector is 150m to the right.
