Park on the big parking of Cuvier. From here take the SB6 (blue striped marked path) or walk with the big path Route Mory de Neuflieux. If you walk with the blue path some boulders are just next to this one. Taking the bigger path you will easily find the area of duroxmanie by turning left after around 400m to Route de Bellevue. The duroxmanie "Area" is along this path after about 80 meters.
