A famous train called El Chepe rides through the canyons over many bridges. The ride shows amazing views of cliffs, rivers, and forests.
The Raramuri people live in the canyons and are known as some of the best long-distance runners in the world. They can run for many hours over rocky trails.
High up the air is cool and fresh, and it can even snow in winter. Down in the deep valleys it stays much warmer.
