Four times the size of the Grand Canyon, Copper Canyon is one of the most dramatic panoramas in the world. Man's greatest engineering feat within this defiant geography is the railroad which traverses it. Almost 100 years in the making, the tracks climb from sea level to nearly 8,000 feet, crossing some of the highest bridges in the world and 87 tunnels including a mile-long, 360 degree spiral. This rail line is rated one of the most scenic train routes in the world. You'll never forget this diverse trip from deserts to mountains, forests to tropical coastlines. Every day is a highlight.
