By car, drive up from Esterençuby and the Sources de la Nive to just before the Col d'Orgambidé, park next to the enclosure, to the right of the intersection of the D428 and the road coming from Spain.
(S/E) Follow this same road until the next junction at Col d'Orgambidé.
(1) Cut across the meadow, heading roughly south-east. The idea is to end up on the ridge of what some people call the Monts d'Orion.
(2) Follow it to an altitude of 1,090 metres, keeping the same direction.
(3) Descend, heading due south, along the animal trails. Cross the road and continue towards the stream that can be seen a little below.
(4) Follow it, or what remains of it, as it seems to disappear underground, and cross its bed heading west towards the meadow that forms a passage through the forest. At the end of this meadow, find a proper path and follow it.
(Entrance or exit of the forest)
(5) Enter the forest via this path that crosses it. Shortly after leaving the forest, the path begins to descend. Look for a signpost on the left and above (towards the west).
(6) (1065m) Head towards this signpost, but as soon as you reach the ridge that slopes gently down towards the north-north-west, follow this ridge.
(7) From there to the summit, climb up the meadow heading west-northwest, gradually approaching (each person can choose their own route, more or less facing the slope depending on their mood and fitness level) the rocky ridge above. Finally, follow it to the summit (1409m). To reach the summit, make your way between the rocks, keeping due north.
(8) Descend the meadow north then north-west until you reach a path that turns into a tarmac road. Follow it for about 1 km.
(9) Leave it on the right at a 180° left turn, entering the forest (1230m).
Descend between the meadow and the forest, heading generally east-northeast then east-southeast until you reach a carriage road (1110m).
(10) Follow it until it turns right towards some huts and continue south-east horizontally (1140m) across the meadow, which will soon begin to descend gently as it approaches the rocky ridge on the left.
Find a way down north towards a hut.
(11) Take the path that leads there and follow it to the road that takes you back to the starting point (S/E).
