Before or after the bridge over the Argens on the D7, take the Route de la Maurette and head for the car park (PB) to the west-south-west of the Rocher de Roquebrune.
(S/E) Turn your back on the road and follow the blue markings. After a short steep descent, join the red and white markings of the GR®51.
(1) Turn right onto a pleasant, easy-to-follow path through the woodland. You’ll reach the large crossroads at Haute Rouquaire.
(2) Head right, towards the south-east, and follow a fence. You’ll reach a junction of paths.
(3) Turn left, leaving the GR® markings, and follow the signs for Les Trois Croix: yellow PR® markings. Follow the path to reach the foot of the Rocher de Rochebrune. Begin the actual ascent, which includes short difficult sections equipped with safety cables or chains. Reach Les Trois Croix and enjoy the sweeping panorama.
(4) Descend via the same route as the ascent: extreme caution is advised on the return to the car park (S/E).
