To visit the Barrancas del Cobra, or Copper Canyon by Train is the best way to see this natural wonder. The Sierra Tarahumara of Chihuahua, where you’ll see one of the largest and deepest canyons in the world, is known as Barrancas del Cobre (Copper Canyon) and it’s one of Mexico’s most awe-inspiring regions.
To visit this area of Raramuri Indian culture, it is recommended that you climb aboard the Chihuahua-Pacifico train (Copper Canyon Train), commonly referred to as CHEPE. The route begins in Ojinaga and the train makes stops in the cities of Chihuahua and Chauhtemoc, where you’ll see various Mennonite colonies.
The train continues along the Sierra de Creel, a mountain range that lies 2,400 meters (7,920 feet) above sea level. It then runs past the Divisadero station and descends through canyons, tunnels, and ravines that border the edges of the majestic Copper Canyon and the Tararecua and Urique canyons. Along the route, the train crosses 37 bridges and goes through 86 tunnels before arriving at Los Mochis, in the state of Sinaloa.
