Grand Canyon National Park is one of the United States' oldest national parks and is located in Arizona. Within the park lies the Grand Canyon, a gorge of the Colorado River, considered to be one of Seven Natural Wonders of the World. Most visitors to the park come to the South Rim entering through the South Entrance, near Tusayan, Arizona, and heading eastward, leaving the park through the East Entrance. Park headquarters are at Grand Canyon Village, a short distance from the South Entrance, being also the center of the most popular viewpoints. Some thirty miles of the South Rim are accessible by road. A much smaller venue for tourists is found on the North Rim
