With bears, buffalo, elk, wolves, moose, pronghorn antelope, bighorn sheep, bobcats, not to mention lots and lots of cattle, Wyoming is full of four-legged creatures that can make your visit a memorable one. The terrain the animals tread is an attraction in its own right: The state is blessed with two of the country's most spectacular national parks, Yellowstone and Grand Teton. With its spewing geysers, bubbling hot pots and colorful canyons, Yellowstone is still one of the most impressive pieces of wilderness in the U.S. And Grand Teton's scenery wildflowers set against a backdrop of craggy purple peaks is hard to beat.
