Follow le Chemin du Rocher de la Reine, turn left at la Route du Liteau (TMF), then right at la Route de la Goulotte; the boulder is 250m on the right after the aquaduct. La Route du Liteau can also be reached from the parking lot of la plaine de Chanfroy by following the homonymous path and then l'Allée des Fusillés on the right.
