Lots of terrain, close, very few things.
Icy, worst snow in the front range, crowded, undistinguished terrain
Unless you are a beginner or a park rat, I highly recommend avoiding this awful resort. Keystone receives the absolute worst snow in the front range year in and year out and should be nicknamed "Key Ice." This place is an absolute zoo on the weekends and is extremely hard to get around if you want to explore the Outback and back bowls. If you are an advanced skier, steer clear because the back bowls get super crusty and icy (don't waste your money on the cat), mogul runs also get skied out in about two seconds and the tree runs in the windows are terribly, un-enjoyably tight. Don't fall into the trap of the "convenient" resort!
