Badlands National Park
Interior, South DakotaO, give me a home where the buffalo roam! With nearly a quarter-million acres of wilderness and the nation's largest expanse of grassland, Badlands is home to bison, big-horn sheep, mule deer, 400 different plant species, and 69 different varieties of butterfly. But this same land once was roamed by rhinos, camels, and three-toed horses, and before that, was covered by saltwater. There are 65 million years of geological history on display here, with varicolored buttes, spires, and pinnacles forming a dreamlike landscape. For exploring it, the Fossil Exhibit Trail and the Cliff Shelf Nature Trail are both kid-friendly.
