Since the early 1900s, West Yellowstone has provided a tourist-friendly gateway to the geysers of Yellowstone National Park and its resident bison, bears and elk. This Rocky Mountain enclave in southwestern Montana is an outdoor enthusiast's dream, offering snowmobiling, cross-country skiing and dog sledding in winter; trout fishing in fall; birding, biking and hiking in spring; and summer parades and rodeos. In-town eateries and attractions are an easy stroll from local lodging.
