The departure point is the car park on Boulevard Louis Pierotti, which can be reached by bus No. 23 (CC Sormiou stop) from the Rond-Point du Prado metro station.
(S/E) Go through the DFCI firebreak gate and follow the red markings along the Vallon de la Jarre to the Fontaine de Voire, then 100 m further on to a junction of three paths.
(1) Take the path on the left (yellow No. 4a), which climbs quite steeply. You will soon reach a small ridge, then the trail swings to the other side, descends a little and heads south along the hillside; the trail enters the Lacroix chimney and, after climbing about 20 metres, reaches a junction with a trail also marked in yellow (No. 4).
(2) Follow this path to the right and, after a steep climb, you will reach the Col des Trois Pics and then, 150 m further on, the Homme Mort plateau. At the point where the trail emerges onto the ridge (see photo "the trail emerges onto the ridge"), leave the yellow trail on the right (due west) and take an unmarked trail that heads southeast towards a large cairn located at the highest point of the Homme Mort plateau.
(3) At the cairn, join the blue trail and follow it eastwards to the Col de Cortiou.
(4) From the pass, head due west, following theGR®® 98-51trail slightly downhill, taking care not to take the green trail that branches off to the left. You will reach Plan de Coulon, where the trail crosses the brown trail that climbs up to the Cirque des Walkyries.
(5) Leave theGR®®98-51and follow this brown-marked trail towards the cirque. The trail climbs gradually then steeply, ending with a short section equipped with a rope (Pas supérieur de la Melette). Reach the plateau and join the green-marked trail.
(6) Follow this path, which heads due north, crosses the Blue and then the Yellow paths, and enters a scree slope before reaching the Fontaine de Voire.
(1) From there, follow the same route as on the way up, in the opposite direction, to return to the car park (S/E).
