Montrouget Est (Biological reserve)
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.
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.
