The Keystone Ski Resort is the home to Colorado's largest night time skiing experience.
You can enjoy the long groomed runs on Dercum Mountain and the Terrain Park until 8:30 pm.
My sister Paula and her husband, Ken, tried it one night last week and while they found it to be a unique, fun experience, it's also dangerous. It's very hard to see with the shadows cast from the floodlights and the skiers have to dodge the large number of boarders jumping several feet in the air.
The best part of night skiing -- you can use your same day ticket to ski at night. Currently, night skiing is available from Wednesday to Sunday; but check the website as the days will change closer to the end of the season!
Paula came up with a great idea -- if you plan to try night skiing, wear a reflective, fluorescent vest so the other skiers can clearly see you.
