Yellowstone National Park
Mother Nature took her time when she went to work on Yellowstone, America's most dramatic natural playground. Upper Geyser Basin contains at least 150 gushers, including Old Faithful, while the park's canyon country is host to hundreds of hiking trails that lead to one grand overlook after the other, including inspiring Artist Point and the wonder called the Grand Canyon of the Yellowstone. Yellowstone's myriad sights and activities are ideal for both thrill seekers and families (or thrill-seeking families).
