In the heart of the Sierra Tarahumara are the majestic Copper Canyon, named for the coppery tone of its walls. They are the longest and deepest canyons, even more than those of the Grand Canyon of Arizona. Its imposing copper walls protect legends, traditions of the Raramuri or Tarahumara who preserve their ancestral lifestyle. These canyons have been their home for centuries and their lives are intertwined with the mountains. The peak moment is when you arrive at the Mesa de Baca Jiparé before the spectacular sight due to the union of the Copper, Tararecua and Urique canyons, the latter with 1879 meters deep, a beautiful landscape that looks much more during the summer for the intense green of the vegetation at its point.
