From the parking, follow the GR58 along the valley floor, as the road bends back on itself, start to climb up the slopes near ravine de Clapouse to the height of 2448M. Turn northwest and climb up a small valley to the ridge. From the ridge go west under the north face of the Pic Beal, once under the obvious north couloir of the pic beal climb to the top of the couloir. The couloir leads on to the steep east facing slopes traverse these until you can climb again to the main ridge.
Follow the ridge till the south face opens up.
Ski down an open bowel and then turn east to an easy angle ridge, ski down this until it flattens a little and some rocks, from here I have skied both sides of the rocks it can be tricky to find, you are looking for a steep couloir /slope. As the angle eases head north a short way and then descend again through a small couloir; then traverse back to the ravine de Clapouse slopes and back to the road to the parking.
