If you want to ski down the mountainside, you'll need to reach the top of it first. Jump on Rouet Ski Lift and enjoy the ride up.
You'll have sightseeing choices galore when visiting Saint-Sorlin-d'Arves. Rouet Ski Lift is a great place to kick off here, but there are many other worthwhile places to appreciate. Pass of the Iron Cross, TSF de la Lauze, and Col du Glandon are near the mountainside transportation system and will fill in your day nicely.
