Departure from the upper station of the Mémises cable car. Access to the Thollon-les-Mémises station via the D24 from Evian-les-Bains, Maxilly or Lugrin. Pass the main town of Thollon and, at the station, there is a large car park on the left-hand side of the road. The departure station can be reached on foot via a small road that branches off to the right after passing the car park.
(S/E) At the cable car arrival area (east side of the station), take the track that heads due east, climbing towards a windsock (ignore the track that descends to the left and the one that heads slightly to the right on flat ground). Immediately pass a first paragliding launch area and, at the fork, follow the track that heads straight ahead (ignore the path that climbs left along the ridges). After about 1km on a slight incline, go around a reservoir on the left.
(1) Leave the Frasse chairlift arrival point on your left, turn right (southeast) and pass a second reservoir on your right. Then turn right onto a path that is not shown on the 1:25,000 map (but is visible when zooming in), leaving the Chalets des Mémises higher up on the left. You will reach the start of the Borée ski lift.
(2) Leave the hut on your right and take a steep, stony track. After a few dozen metres, ignore the grassy path on the right and continue on the track that climbs diagonally and crosses the Phébus ski lift line.
(3) At the Parchet chairlift line, turn left at a right angle and cross the Phébus ski lift again. Then turn right (south-east) and climb up a grassy slope (the "Les Myrtilles" ski slope in winter), keeping the Borée ski lift at a distance on your left. This will take you to the top of the Parchet chairlift.
(4) Go around the top of the chairlift on the left (the purple line on the IGN map is inaccurate here) and follow a well-marked path that leads to the foot of a couloir in the middle of the Borée "cliffs". Climb this rocky couloir, using a permanent rope if necessary. At the end of the couloir, follow the ridge to the right, which leads very quickly to the summit.
(5) The descent follows the same route in reverse to the cable car (S/E).
