This week the town is aflutter with Hollywood celebs and wannabes as the 17th annual Sundance Film Festival takes over through Jan. 24. Though the streets and restaurants are packed with glitterati and Looky Lous, it's not too late to book; there's still room at the lodge. And if you just want to play in the snow, there's plenty of thrill-seeking fun. Tara Weingarten, a special correspondent in the Los Angeles Bureau, loves to visit Park City in the winter, but this week she's happy to watch all the stars jet away and leave Tinseltown's freeways a little less congested.

Ski and Snowboard: Not surprisingly, the runs are empty this week, as most visitors are desperate to catch a celeb or see the next blockbuster flick. If you're game, hit the challenging Canis Lupus run at the Canyons ski area, which is also a great place to stay, with rooms—many with kitchens and fireplaces—still available (thecanyons.com). Loved for its milelong natural halfpipe, which doles out radical banks and turns, it starts at 10,800 feet. And if you're really an adrenaline junkie, hop onto the less crowded DreamCatcher and DreamScape lifts, where you'll find fresh powder even days after a snowstorm.
