See MAIN PAGE / "Getting There" to get to the base of the climb, Cabane de Tracuit.
"The Alpine 4000m Peaks by the Classic Routes" by Richard Goedeke (1991) says on page 106:
"From the hut take an easterly line over the Turtmann Glacier to its Eastern arm, keeping well away from the drop to its NE (potential cornices). Go steadily up the slope of the NW face to the notch between the two summits and turn right and ascend the ridge, often corniced, to the highest point. 2-3 hours, a departure at 5 or 6 a.m suffices".
Rope, crampons and ice axe may be necessary. Also take warm clothes with you.
