Aspen Snowmass Nordic Trail System, Aspen

It is rare that the word "free" can be attached to anything in Aspen, which is why this cross-country center is all that much more special. It provides over 90 kilometers (56 miles) of groomed tracks, making it a perfect (and free) alternative to downhill skiing. There is an on-site pro shop to rent or buy equipment, as well as waxing, tuning and repair service. For those who are new to the sport, or would like to brush up on their skating techniques, lessons are available. In addition, there are also his and her locker rooms, a warming hut and a public ski waxing room.
