Isolated roof in a natural bivouac on a small and quiet square along the bue path. Start to the left of L'Odyssée de l'Espèce underneath the roof, traverse to the right, climb the right arete and exit in L'Espèce de.
From the N7 (direction Fontainebleau), turn right at Le Carrefour du Grand Veneur, take the D301 and park the car 200m to the right after the bend. Follow the blue path n°6 for 10 minutes; the boulder is just after the crossing of the paths n°6 and n°6.6.
