Consider these statistics: Yellowstone National Park receives about four million visitors a year. Ninety percent of them see the park between May and September. Less than four percent of visitors come between December and March. And yet, in many respects, winter is the best time of year to see Yellowstone: Wildlife congregate at lower elevations, making them easier to see (except bears, of course), waterfalls form towering columns of ice (like 308-foot Lower Yellowstone Falls, in the lead photo, above), and the geysers and other thermal features take on a different character when the landscape grows hushed under a thick blanket of snow.
Plus, you can see the park’s major features, like the Upper Geyser Basin—home to Old Faithful and one-fourth of the active geysers in the world (and the greatest concentration of them)—on skis. Cross-country skiing groomed trails in Yellowstone, many of which are beginner- and family-friendly, is one of the coolest experiences in the National Park System.
