Yellowstone National Park is a visionary gift that was bestowed upon the world on March 1, 1872. On that day, Pres. Ulysses S. Grant signed the bill that created the world's first national park. Filled with natural wonders and inspiring scenery, it is home to some of America's rarest and wildest species. Its natural appeal is enhanced by the thrilling display of wildlife living within the park boundaries. More than three million visitors a year pass through the park's portals and enter "Wonderland."
