(2) At the Col de Corbières signpost, continue along theGR®91path.
(3) Leave theGR®91via the path on the right, marked in yellow, towards La Vanige. The climb to the summit is very steep (Effort 5) with gradients of over 20 per cent but without any particular difficulty (E5 T1 R2).
(4) From the summit, follow the path along the ridge to its end.
(5) Then continue the descent to the left, on the western slope, towards the Rocher Percé.

(7) At the Corbières signpost, head east along the yellow-marked path leading to the Col de Haute-Huche and the Croix de Roussieux. You will come to a junction you passed on the way there.
