The Copper Canyon is actually six distinct canyons that form a single network. Each canyon has its own river in the canyon floor, all of which merge into the Rio Fuerte. Taken as a singular unit, the Copper Canyon greatly outsizes the Grand Canyon of Arizona. Depending on what statistics are used, the canyon is between four and seven times bigger than its American counterpart. At its deepest point, the Copper Canyon is 1,462 feet deeper than the Grand Canyon. The park that hosts the canyon system is an enormous 155 miles wide and 372 miles long.
