If you want to ski down the mountainside, you'll need to make your way to the top of it first. Hop on Envers Ski Lift and enjoy the ride.
You'll be spoiled for sightseeing choice in Villarembert. Envers Ski Lift is a great place to kick off here, but there are lots of other worthwhile places to check out. Opinel Museum, Pass of the Iron Cross, and Museum of Costume and Popular Traditions are not far from the mountainside transportation system and and will cap off your day nicely.
