terrific variety of terrain, huge and uncrowded, good lifts
Not near a major city but thats why it is uncrowded
I've skied everywhere in the western US and Big Sky is as good as it gets, and no I don't work for the resort. The terrain is great no matter what level you ski, and huge. So you can ski expert, intermediate or beginner and do it on long uncrowded runs with short if any lift lines. There are plenty of great accomodations and restaurants. No the nightlife is not comparable to Aspen, but if you choose ski areas for the skiing you will not be disappointed!
