Park City at Night, Utah, USA

Robert Redford's indie filmfest Sundance has turned Park City from an also-ran ski resort into one of the hottest winter destinations since it first appeared three decades ago. The 10-day extravaganza runs January 19-29, and should draw similar star wattage as last year, when Ewan McGregor, Lena Dunham, and Kerry Washington hit the frosted red carpet. For star spotting, book a table at the town’s hottest new restaurant, chef John Murcko's Firewood, with its open-plan kitchen and flame-grilled menu, or local mainstay The Eating Establishment, which Modern Family’s Ty Burrell just relaunched. Warm up with a dram or two of local whisky at High West Saloon—or head to the ranch which houses its distillery in nearby Wanship for newly offered tours.
