Grand Canyon is one of the oldest U.S. national parks and is located in Arizona. Within the park lies the Grand Canyon, a gorge of the Colorado River, considered one of the greatest natural wonders of the world. The park covers 1902 km ² (4927 km ²) of unincorporated Coconino County and Mohave County.
This is the most impressive sculpture of nature, carved by the Colorado River over millions of years. You’ll have a bird’s-eye view as you explore the falls off the tracks and monuments by air. In addition, a raft trip down the Colorado gives another perspective on the timeless beauty of the canyon. Magnificent sunrises, sunsets, and the stations are here to enjoy their free time.
The area around the Grand Canyon became a national monument on January 11, 1908, and was designated a national park on February 26, 1919. The creation of the park was an initial success of the conservation movement of the environment, 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 upstream flooding and the creation of Glen Canyon Lake Powell.) UNESCO has declared it a World Heritage Site.
The Grand Canyon itself, including its extensive system of tributary canyons, is valued by the combination of great size, depth, and the exposed layers of colorful rocks dating from Precambrian times. It was created through the incision of the Colorado River and its tributaries, after the Colorado Plateau was raised and the Colorado River system developed along its current path.
