lots of terrain, easy to get to, night skiing, A-51
icy, low snowfall totals, can get crowded
I ski at Keystone alot because i live so close. My biggest compaint is the lack of snowfall in recent memory. The runs can get very icy, escpecially in the front. When there is snow it can be fantastic. If you go early you can get in a few nice runs, they do a pretty good job of grooming. Night skiing is a pretty cool aspect too. They have a lot of expert terrain when theres good snow coverage but personally I'd like to see more intermediates for the days I'm feeling lazy.
