From Plan de Baix, follow the D578 towards Omblèze. At the exit of the gorges, turn right towards the town hall (Mairie-Salle Communale) in Les Arbods. In the hamlet, follow the signs for the car park: Salle Communale-Randonneurs.
Park below and walk to the start of the hike at Place Patrick Duc, in front of the town hall.
(S/E) Take the paved road between the houses, opposite the town hall. Pass the hamlet of Pierroux and continue along a track at the bottom of the valley. Leave the trailhead on the left towards Les Sarnats and La Tête de la Dame and continue towards Col des Teulières, Bec Pointu. After crossing a stream, the path turns left uphill. Continue to a crossroads a few metres further on, at the bottom of a meadow.
(1) Be careful not to continue straight ahead; turn right onto the less marked path. Cross the meadow and pass under the Grange Neuve building. The path becomes more marked and heads towards the Montagne des Teulières. Follow it and leave a trail on your right at the first hairpin bend.
Continue climbing and after several hairpin bends, a well-marked trail branches off to the left at a right-hand bend. This allows you to cut through the woods a little before rejoining the path. At the bottom of the valley, cross it, continue for a few metres and find a trail on the right.
(2) Follow this trail uphill. The trail follows the left side of the valley without straying too far from it. Ignore any trails that branch off in the opposite direction and join the ridge at the Col des Teulières.
(3) Take the path on the right that follows the summit. Cross a wood, arrive at some grassy areas and continue to the summit of Bec Pointu via a final fairly steep climb.
(4) Descend from the summit by following the ridge along a less distinct path. Reach the Col Bernard.
(5) Begin the climb towards the summit of Courcousson and pass the first ledge. On the flat section, under the rocks of the peak, turn left, almost horizontally. Find a small, barely visible path between the box trees. To help you find your way, this path follows, more or less, the bottom of the rock slabs that you can just see. This section is easy to cross. Reach the Pré des Chau meadow, just above the wooded area that extends into the meadow and at the bottom of the steep slope from the summit of Courcousson.
(6) Follow the grassy slope, staying on the highest part, until you see a large stone standing about 60 cm high and a post indicating the Crête d'Omblèze, about 50 m before the end of the ridge.
(7) To get around the ridge, turn right as you descend. The path, which is not very visible at first, enters the woods and zigzags downhill. Pass a rope handrail, then the path turns left along the side of the hill to rejoin the ridge. Continue until you find a small pass and a clearly visible crossroads, signposted Col d'Omblèze.
(8) Turn right, and the trail descends gently to the telecommunications relay station at Col des Ayes.
(9) Continue along the track, taking the path on the left after the third crossing of the valley. Follow the bottom of the valley, crossing the track twice, then follow the track. Pass the hamlet of Les Blaches and return to the car park at the town hall (S/E).
