1. January: Colorado
It’s no secret that Colorado ski resorts are among the country’s best, but that's not all this state has to offer outdoor enthusiasts in the winter. Try your hand at heli-skiing (that's dropping from a helicopter rather than a ski lift) in the backcountry at Telluride, bask in natural hot springs after your ride down the mountain in Steamboat Springs, or embrace winter camping and dog sledding at the refurbished mine town of Dunton Hot Springs, where you'll find an Old West saloon, the opportunity to ice climb and, of course, more hot springs.
