In the remote Sierra Tarahumara Mountains, Mexico’s Copper Canyon system is longer and deeper than the Grand Canyon in Arizona. Native Raramuri people live in and around the canyons. The Raramuri are famous for their long distance running abilities, and there is a maze of foot trails all around the canyons, where visitors can hike with the help of a guide. Adrenaline-pumping adventures abound in the Copper Canyon, from white-water rafting the Ulrique River to visiting an adventure park along the canyon for ziplining and rock climbing. Or simply take in the spectacular views. The scenic train ride from Chihuahua offers opportunities to stop and sightsee along the canyons.
