The night skiing at Keystone is AWESOME! My boyfriend and I have been coming to Keystone since the start of the season, but since we discovered the night skiing that is all we come for. The crowds head out and sometimes we are the only 2 people cruising down the mountain on parts of the runs. It is an exhilarating feeling- we really love it! I do wish the night skiing went until 9pm, however- that would be one more hour of pure fun!
