Yellowstone National Park is the first national park established in the United States. Located in Wyoming, the park's highlight is the 1,000-foot-deep Grand Canyon naturally carved from yellow rock with the rushing waters of Yellowstone River. Old Faithful Geyser, free-roaming bison and steaming pools fueled by the world's largest supervolcano are just a few of the attractions at this 3,468-acre park. Plan your trip to Yellowstone to ensure you see everything on your wish list and experience as much as possible while traveling through the park.
