Mid-December to early March, Yellowstone is a winter wonderland best explored on foot, cross-country skis, or snowshoes. The park stays open year-round, but in winter most roads are closed to wheeled vehicles. "Lodging and Learning" packages offered by Yellowstone National Park Lodges and the Yellowstone Association Institute make it easy to stay and play in the park.

The packed winter trails crisscrossing Chena State Recreation Area's 397 square miles of forests and alpine tundra are open for snowshoeing, cross-country skiing, snowmachining, and winter mountain biking (try the Colorado Creek Trail for a three- to four-hour ride). Located only 26 miles east of Fairbanks, Chena River puts Alaskan adventure within easy reach via scenic (and plowed) Chena Hot Springs Road.
