Take the the gondola up to the top. The ski down the most obvious way down. There is a big vally (which is what Canalone means) leading down the mountain.
Big open vally to ski in. No obvious dangers. This is a classic alp ski decent and in perfect conditions its a drream. There are various routes if you want to ski steeper runs or jump some cliffs. But all of them are pretty obvious. In the photo its the part in the shadows.
Respect the avalanche work done by helicopter before skiing.
