Departure from Sevan, reached by a small road that climbs steeply from La Chapelle-d'Abondance (follow the sign for "Lac d'Arvouin"). Parking at the end of the road.
Directional signs are present at important locations. They are recent and in excellent condition from the start (S/E) to the Col de l'Outanne (4). After that, either the sign is on the ground or it has been completely removed (situation in August 2018). At the start of the hike, there are also a few signposts with double yellow arrows.
(S/E) Take the track heading north-east that climbs up the road towards the Col de Braitaz via the Col de Recon (do not follow the signs for "Le Linla 1h40"; the corresponding path, which climbs up to the left of the track, will be the way back). Pass under the Braitaz chairlift line. Ignore a path coming from the left (signpost) and turn right onto the track that climbs gently into the forest.
At the signpost "Sous le Col de Recon", stay on the track that turns left in a hairpin bend. After a few dozen metres, you will see the summit of Linleu on your left and the route leading to it. You will quickly reach the Col de Recon.
(1) Continue on the track towards Braite and the Col de Conche (yellow Swiss signposts). Pass under the ski lift line, with the gantry bearing the "turn around" sign on the left side of the track. At the fork that follows immediately, ignore the track that descends to the left and continue straight ahead to reach the Col de Braitaz.
(2) Go around the arrival area of the Braitaz chairlift on the right. Then walk along the bar-restaurant and a hut, keeping both on your right. Follow a fairly flat path until you reach a junction with a path coming from the left (signpost).
(3) Continue straight ahead towards the Col d'Outanne. Cross a small scree slope at the foot of the Aiguille de Braitaz. Then climb up a steep but well-marked path, as close as possible to a rock face. This will take you to the Col d'Outanne (signpost across the path).
(4) Head west on the trail that crosses the top of a grassy valley and quickly arrives at the Col de Sevan.
(5) Turn right and take the path that climbs up the ridge. Follow several switchbacks, then go around the rock faces on the left, in a small corridor where the path remains well marked. At the end of this corridor, turn right (east). Then turn left and follow a few switchbacks to reach the ridge below the summit (cross).
(6) Follow the ridge to the left to quickly reach the summit (boundary marker). Be very careful due to the steep drops to the north.
(7) The descent starts along the same route as the ascent. Descend to the Col de Sevan.
(5) Turn left to join the path to the Col d'Outanne.
(4) Turn right towards the Col de la Conche (Swiss name for the Col de Braitaz). After crossing the small scree slope again, reach the junction of the two paths (sign).
(3) Leave the path you took on the way up and turn right, heading downhill towards Sevan (south-southeast). You will come out onto an alpine track. Follow it to the right (do not cross the Braitaz chairlift line). Pass a flat area marking the site of the former Chalets de Braitaz (now demolished).
(8) Just before the track starts to climb again, look for a trail on the left that descends into a small valley and passes at the foot of a peak on the right (elevation 1799). Descend into the valley on a faint trail, parallel to but at a good distance from the Braitaz chairlift line. Keep to the right to pass above a cluster of spruce trees and rejoin a well-marked trail. Continue downhill and you will reach Sevan ahead (S/E).
