Start with a tour wildlife watching at the park, then dine cowboy-style at a Western cookout. Horseback riding? We have that, too. Catch trout at Hebgen Lake, or fly fish a famous stream. Zipline at Yellowstone Aerial Adventures, or check out the locals at the Grizzly and Wolf Discovery Center. View classics at the Rod Run Car Show. And there's plenty to do in winter, too, including cross-country skiing (50-plus kilometers of groomed trails), snowmobiling, the Snowmobile Expo and Races, and the Yellowstone Ski Festival. Plus, kids can try a new winter activity at Kids'N'Snow, a one-weekend-a-month event for families from December to March.
