Thanks to several large snowstorms more than 3,300 acres are open to the public at Big Sky Resort in Montana—that's more than any other ski area in the Rockies. And to spread the stoke, Big Sky has recently offered to share their terrain with Epic Pass holders through the end of January.

The home of the "Biggest Skiing in America," Big Sky currently offers 3,381 acres of open terrain (with 100% of lifts up and running) and 4,350 vertical feet to make your legs burn. Whether you're one to shred groomers or one to charge the chutes off the Lone Peak Tram, Big Sky's variety of terrain will not disappoint. Big Sky also recently opened five new gladed runs for those of you tree-seekers out there.

Vail Resorts' Epic Pass holders will be able to take advantage of Big Sky's terrain throughout January. Big Sky will honor the Epic Passes of those who book their lodgings with Big Sky Central Reservations. When booking, be sure to ask for the "Epic Package." Big Sky will also extend the Bring a Buddy Coupon to Epic Pass holders, allowing friends in their reservation who don't own an Epic Pass to ski for just $74/day.

*Bozeman Airport offers 35 direct flights to and from Denver and 14 to and from San Francisco each week, as well as direct flights to and from eight other cities and hubs. Visit bigskyresort.com/epic or call Big Sky Central Reservations at 1-800-548-4486 for more information.
