At the Grand Canyon's South Rim, it is nearly 1 vertical mile, or approximately 5,000 feet, from rim to river. At its deepest point, it is 6000 vertical feet from the canyon rim to the Colorado River. At Grand Canyon Village, the canyon is 10 miles wide, although, in other places, it is as much as 18 miles wide.
Traveling to the bottom of the Canyon and back, on foot or by mule, is a two-day journey. A rim-to-rim journey typically takes three days to travel from the North Rim to the South Rim. A trip through the Grand Canyon by raft can take two weeks or more.Learn more about United States
