Park where the road closes on the way to Mikeou (normally around Truchet). From there skin up the road to Mikeou and at the buildings enter the trees. There are a series of paths and a road leading up the hill side, often the skin tracks will pick the best line between these heading up. Make your way up to the Crete de la Breche where the trees start to thin out, from there head up the open ground to the summit.
Ski back down the same way, sticking to the east facing slopes is best and gives you a great run in well-spaced out trees.
