Corbeau vonne's line.

A long hike is needed (30-45 minutes) to reach this line. Take a left from the "Culet 1 or 2" ski lifts, or right from the "Chalet neuf 1 or 2" ski lifts and hike up the top of the "Bec du corbeau" peak. The entrance is a long traverse on a ridge devoid of trees. The line gets a lot of sun which can make the base pretty weak and result in avalanche danger. A good weather window will be needed due the time needed to access the line, lowest part will be really steep with trees all over the way with high avalanches risks, blue slope "La Forestière" will be join at the end of the line, bringing you back to "Portes Du Soleil" or "Gabelou" chairlifts.
