It has great snow and terrain!
The food could be better
Big Sky is the best ski area I have ever skied and I have skied at Snowbird. There was only one thing I didn't like. You had to take a shuttle to the resort (unless you stayed at the Mountain Inn). Then you had to walk to the ticket office. I probably wouldn't of cared so much if I hadn't of injured my leg by running into a tree skiing.
If you like powder bowls go to the Lone Peak triple and to your left there is a bowl. If you like black diamonds go up the Lone Peak tram or go over to the Challenger lift.
