Grand Canyon National Park is one of America's 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 the major natural wonders of the world. The park covers 1,902 mi² (4927 km²).
Most visitors to the park come to the South Rim, arriving on Arizona Highway 64. The Highway enters the park through the South Entrance, near Tusayan, Arizona, and heads 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, accessed by Arizona Highway 67. There is no connection by road between the two, except via the Navajo Bridge, entailing a five-hour drive. The rest of the Grand Canyon is extremely rugged and remote, although many places are accessible by pack trail and backcountry roads.
The area around the Grand Canyon became a national monument on January 11, 1908 and was designated national park on February 26, 1919. The creation of the park was an early success of the environmental conservation movement; its National Park status may have helped thwart proposals to dam the Colorado River within its boundaries. (Lack of this fame may have enabled Glen Canyon Dam to be built upriver, flooding Glen Canyon and creating Lake Powell.) UNESCO has declared it as a World Heritage Site.
The Grand Canyon itself—really an extensive system of tributary canyons— is neither the largest or deepest canyon in the world, but is valued for the combination of large size, depth, and the exposed layering of colorful rocks dating back to Precambrian times. It was created by erosion from the Colorado River and its tributaries.
