I spent 3 consecutive days at Big Sky. Main lifts were no wait and high speed, expert terrain lifts were slow 2 person chairs which was ok. Snow was well groomed. I loved the long, wide trails. For experts, I'd recommend the Challenger lift which ends on a narrow peak that services several expert chutes. I didn't ride the tram to the peak, long lines and only 2 cars to service the very top. This resort is comparable to the best Colorado resorts. My only complaint is it's often times windy and the lifts are shutdown till winds subside.
