Yellowstone National Park
Yellowstone National Park is one of the most popular national parks in the U.S. Its uniqueness lies in that it features multiple natural wonders all in the same park. Geysers, hot springs, a grand canyon, forests, wilderness, wildlife and even a large lake can be found inside the park. The list of activities for visitors is nearly endless; from backpacking to mountaineering, kayaking to fishing, sightseeing to watching bison, moose and elk wandering into the parking lot of the visitor center. And in winter, the park offers hundreds of miles of groomed trails for snowmobiling.
