Alta is one of those places that you have to experience to believe. Alta gets more then 500 inches of snow a year and it has the best powder skiing anywhere. Usually over the course of the year we ski in hip deep powder at least a half-a-dozen times. I've skied a lot in the Northeast (on ice), Colorado, Idaho, etc. Alta has the best and most varied terrain and the absolute best snow on any mountain. It's very reasonable for a lift ticket which ran about $34 last year and the lift lines are very short which insures that you'll get your money's worth. On a good snow day leave early as the canyon road (for the most part) is a single lane so traffic gets congested from time to time.
Pros: Snow, No Snowboards
Cons: Canyon Road, No Snowboards
