If your looking for pretentious restaurants, beautiful women,fancy lodging that you can ski to the lift from, then try Aspen, Vail,Steamboat, even Keystone. But If you like a simple unpretentious lodge, reasonable food prices, and lots of local skiiers who probably won't run you over and really know how to ski, ABasin is the place! It arguably has some of the most challenging terrain and in 55" midmountain ski base years (good snow years) the bumps on some of the runs are basically huge. I'm an expert skier who is maybe closer to advanced intermediate and A basin has the most challenging black diamond runs. It's not a huge resort like copper , Vail,Steamboat, or Winter Park, but it is still bigger than a a lot of them and it simply has the most expert bang for your buck of them all. I've been going back religiously for the past 8 years since moving to Colorado, and it is still my favorite. It also is a little more affordable and as I said basic, down to earth, no frills skiing except for the runs which are among the best if not the best in the West. It doesn't have huge bowls, but it does have alot of challenging varied terrain. I like the Pavollini side as much as East Wall. It does have some intermediate/beginner runs. Downside, occsasionally the upper basin can be rock hard packed powder. And it isn't great in May even if it is open. On snow days you can have white out conditions up top. Who needs a terrain park when you have so many cliffs/rock outcroppings to fly off ?
