Mexico's Copper Canyon, in the state of Chihuahua, is a network of canyons which together are several times larger than the Grand Canyon in Arizona. It is a beautiful place to visit and the best way to do it is by train on the Chihuahua al Pacifico Railway, affectionately known as "Chepe"!
Thank you for your comments; and yes, from Creel I took the "Chepe" train to the Pacific Coast and it was awesome! This picture was taken from one of the windows of the train.
