The area is access sensitive
All of the forest of Coquibus is protected area called Biological reserve. This means, stay on paths, keep your dogs on leash during the spring and early summer season to give the wild life peace. Do not leave any traces, stash pads etc and behave nicely to other people using the forest.
Park on the big parking showed on map, Walk towards the north with Chemin de la Boulignère. When getting to the 2nd crossing where you have the bench in the forest, either go to the right and then up left the hill to get into the main area, or take the small path up the hill and be a legend by repeating The big island assis.
