Park at Le Casset (tight parking in the village). Follow a ski du fond track west to the Pont du Clot du Gué then continue up the Petit Tabuc valley. Leave the path and cross over to the Torrent du Glacier de Casset. Follow the bowl up the torrent as far as you can, passing the petit couloir Davin on your left. At the end of the bowl you will see the couloir on your left. Climb the couloir, which just keeps going - it is normally a bootpack from near the bottom.

As you near the top the line splits - you can climb left to the access the glacier for a longer and slightly steeper route, or climb right to stay on the classic line of the Davin. The last section is steep and in the rocks so care is needed. The top gives you amazing views down on to the Glacier du Casset.

Now comes the fun part if your legs are up for it! Ski the couloir - it is a good constant angle all the way down. At the bottom of the couloir you can ski back across to the way you came in (a little climb needed), or you can stay on skiers right of the river, this line does join up with your ascent path near a little bridge but can be tight in the trees.
