Access : To the south of Gap in the direction of Barcellonnette, via the departmental road 90 B. 5km after exiting the city at point 658, on the right is a car park of a dozen spaces in which you can park.

Push the right-hand barrier to continue and reach the intersection of spot height 713.
(1) Continue opposite on a gentle climb, fully south, to join a well-marked trail. Follow it south to an intersection 900m further on.
(2) Turn right to reach the Crêtes de Cristayes (sport height 909).
(3). Turn left to reach the highest point of the hike 900m further south. Continue along the ridge descending southwest to join the GR653D.
