Southwest of El Paso and south of Creel in the Sierra Madres in the Las Barrancas Del Cobre National Park, the remote and spectacular Copper Canyon region covers 25,000 sq. miles and is four times larger than the Grand Canyon of Arizona. Also know as Sierra de Tarahumara, it is one of the last great wildernesses in North America. Most hikes start from the town of Creel (stay at Parador de la Montana 14-10-45-80) beginning with rim rides past beautiful waterfalls and hot springs. Then begin the 7,400 feet descent into the canyon with a stop in La Bufa (camping). Continue deeper into the canyon towards Batopilas along a route described as the most scenic in North America. Dont forget a side trip to the Lost Mission of Satevo and a dip in the clear pools of the Rio Batopilas. Next, check out the remote village of Cerro Colorado with incredible singletrack and river crossings.
Other accomodations along the trail include Hotel San Francisco (Chihuahua) 14-16-75-50, Posada Barrancas Mirador (Divisadero) 14-16-65-89, and Hotel Santa Anita (Los Mochis) 14-16-65-89.
The lowest cost option to get to the Copper Canyon is to fly to El Paso (US) and drive south across the border. A popular access point is the town of Creel where you can obtain supplies and maps.
Note: Prior to 1997, the topographic maps developed by the federal government used the NAD27 CONUS datum. Starting in 1998, the government transitioned to the ITRF92 datum (some maps show both datum), which is pretty much identical to the WGS84 datum.
Overall, Copper Canyon Trail is the 4th most popular hiking trail of all 11 hikes in Mexico.
