Car park on the D539 in a bend between Grimone and the Col de Grimone.
The route is well signposted, with numerous directional posts and markings.
(S/E) Walk down the road (D539) for 1 km to a hairpin bend.
(1) Leave the road; do not take the wide path on the right but the small track below which, 100 m further on, joins the path coming from Grimone, which you follow to the right.
Yellow-green markings
(2) Cross the track and take the path on the right which runs alongside the trees and joins a track 500 m further on.
(3) Head straight on towards “Sucettes de Borne”, staying on the main path.
(4) At the crossroads, turn left to follow “Sucettes de Borne”. You’ll reach a junction a good kilometre further on.
(5) Do not take the path that descends to the left towards Glandage. Continue right for 200 m along the forest track.
(6) At the junction with the signpost for Piégu, take the path that descends to the left towards "Sucettes de Borne".
(7) When you reach the Gué junction, take the path down to the left towards "Sucettes de Borne". Continue down the path for 400 m past the Sucettes, to the magnificent rocks further down.
(8) Turn back and head up to Le Gué.
(7) Cross over and continue straight ahead. At the crossroads 200 m further up, turn left towards “Col de Jiboui”. Shortly after crossing the stream, at a right-hand bend, the route leaves the track and climbs, cutting across the bends via a shorter path.
(9) When you reach the Refuge et Lodge d’Alpage de la Tour, remember to fill up with water. Head up the path towards “Col de Jiboui”. At the crossroads 500 m further on, leave the paths and take the track opposite, which climbs steeply up the slope and joins a junction at the Col de Jiboui.
(10) Continue to the right towards “Crête de Jiboui”.
Yellow (GTV) + Red-White markings
(11) On the ridges, follow the ridge path to the right towards “Le Jocou”.
(12) Curiously, the path leaves the ridges and takes a new, rather awkward route, on a slope, a few dozen metres upstream from the old one. Why?
(13) At Col de Seysse, turn right and follow the GR® along the hillside to a track.
(14) Follow it to the left, then, at the hairpin bend, continue along the path to the right until you reach a track.
(15) Head down to the right, then take the path on the left and join the road and the car park (S/E).
