Cruise up to Alta Ski Area and hit their nordic track for the day. It's an awesome 1 mile figure eight loop, perfect for beginners learning how to cross-country ski. Not to mention its free!
Drive up Little Cottonwood Canyon until the first entrance into Alta. Park in the Collins lift parking lot, throw your boots on, and head over to the nordic track. Its just next to the tow rope that runs through Albion Basin. Now thats left to do is to step into your skis and ski. The track has a lot of different variability in the terrain, so you'll find flat, uphill, and downhill. Grooming of the track occurs a few times a week, leaving it always in tiptop shape.
