Grand Canyon National Park encompasses 1,218,375 acres and lies on the Colorado Plateau in northwestern Arizona. It is a World Heritage Site. The Grand Canyon is one of the most studied geologic landscapes in the world for good reason.
The Canyon, eroded by Colorado River, averages 4,000 feet deep for its entire 277 miles. At its deepest point, the canyon is 6,000 feet deep and measures 15 miles across at its widest point. The gorge shows off 2 million years of geology as the Colorado plateau was lifting.
But the Grand Canyon is not just limited to geologic wonder. Over 1,500 plant species, 355 birds, 89 mammals, 47 reptiles, 9 amphibians, and 17 fish species are found in Grand Canyon National Park.
Campground reservations can be made at two campgrounds in the park - one on each side of the rim: the Mather Campground on the South Rim in Grand Canyon Village, and the North Rim Campground.
