If you ask most travelers to name North America’s most spectacular canyon, the answer comes back almost reflexively: the Grand Canyon. But in the rugged Sierra Madre Occidental of northwestern Mexico, a far less visited and, by several measures, far larger canyon system carves through the Mexican state of Chihuahua. Locals know it as Las Barrancas del Cobre. The world knows it as Copper Canyon.
It is one of the most dramatic landscapes in the Americas. It is also one of the most surprising. Here is what makes the geography of Copper Canyon so extraordinary, and why it deserves a place near the top of any traveler’s list.
A canyon system, not a single canyon
The first thing to understand is that Copper Canyon is not one canyon. It is a network of six major canyons, plus dozens of smaller side canyons, all carved by six rivers that eventually flow westward into the Sea of Cortez.
The principal canyons are the Urique, Sinforosa, Batopilas, Candameña, Chínipas, and Septentrión. Each has its own character. Some are lush and tropical at their floors. Some are bone-dry. Some hide colonial mining towns at the bottom. The collective system covers an area of roughly 25,000 square miles, an expanse larger than the entire country of Switzerland.
The name comes from the green and copper tints of the canyon walls, an effect created by oxidized minerals in the rock and by the lichen that clings to the cliffs. In the slanting light of late afternoon, the cliffs glow with the warm metallic colors that gave the region its name.
The size comparison everyone wants to know
So how does Copper Canyon stack up against its more famous American cousin? The numbers are striking.
The Grand Canyon is 277 miles long and reaches a maximum depth of about 6,093 feet (1,857 meters) at its deepest point. Copper Canyon, taken as a system, is more than four times the total volume of the Grand Canyon. The deepest of its canyons, Urique, drops 6,164 feet (1,879 meters), making it deeper than any point of the Grand Canyon and the deepest canyon in North America.
Two other Copper Canyon canyons, Sinforosa at 6,002 feet and Batopilas at 5,905 feet, also rival or exceed the Grand Canyon’s deepest sections.
What Copper Canyon lacks is the wide-open horizontal scale that makes the Grand Canyon visible from space. Copper Canyon is steeper, more vertical, more compressed. It feels less like a vast desert chasm and more like a labyrinth of green and copper walls, plunging suddenly out of pine forest into tropical river valleys thousands of feet below.
A landscape with multiple climates
Stand on the canyon rim at Divisadero, one of the most famous viewpoints, and you are at roughly 7,700 feet of elevation. The air is cool. Pine and oak forest stretches in every direction. In winter, the higher slopes can receive snow. The plateau supports an alpine ecosystem more reminiscent of Colorado than of central Mexico.
Now look down. At the floor of the Urique Canyon, more than 5,000 feet below you, the climate is subtropical. Cacti, agaves, palms, and even bananas grow in the warmer microclimates. River water runs clear over polished stone. Locals farm corn, beans, oranges, and avocados in pockets of fertile soil along the canyon bottoms.
This vertical compression of climates is unusual on the planet. It means that within a single day’s hike, a traveler can move through what feels like four distinct ecosystems, from temperate pine forest to tropical river bottom.
A volcanic origin story
The geology that produced Copper Canyon began about 30 million years ago, when massive volcanic activity built up the Sierra Madre Occidental as one of the largest volcanic plateaus on Earth. Layers of ash, rhyolite, and other volcanic rock built up the high plateau that stretches across modern-day Chihuahua, Sonora, Sinaloa, Durango, Jalisco, and Nayarit.
Then water did the rest. Over millions of years, six powerful river systems carved their way through the volcanic plateau, cutting deeper and deeper as the land continued to lift. The result is the labyrinth of vertical-walled canyons we see today, an exposed cross-section of geological time, with bands of red, orange, gold, and copper rock recording millions of years of volcanic and climatic history.
A wildlife haven
Copper Canyon’s variety of climates makes it home to an extraordinary range of wildlife. The forested rim country is home to black bears, mountain lions, white-tailed deer, wild turkeys, and a recently confirmed population of Mexican gray wolves, the rarest subspecies of gray wolf in the world. Bird life is exceptional, with species including the eared trogon, the rare imperial woodpecker (possibly extinct, with rumored sightings continuing), military macaws, and dozens of hummingbird species.
Down at the canyon floors, the warmer climate supports coatimundis, ocelots, and a remarkable diversity of reptiles and amphibians. Several plant species in the canyon system grow nowhere else in the world.
The region was designated a Mexican National Park in the 1940s and has been considered for UNESCO World Heritage status, a designation many advocates believe is overdue.
The towns clinging to the canyon edges
Two small towns serve as the principal bases for visitors. Creel, at the canyon rim and a longtime logging center, is the larger and more developed of the two, a small mountain town of pine-board buildings, woodstoves, and a frontier feeling. Posada Barrancas and Divisadero, both perched directly on the canyon edge, offer some of the most jaw-dropping rim views available anywhere.
Down in the canyon itself, the old silver mining town of Batopilas, founded in 1632, sits at the bottom of one of the deepest canyons. The road to Batopilas, a winding, narrow ribbon that drops more than a vertical mile, is itself a legendary travel experience.
A landscape designed for slow travel
Copper Canyon does not reveal itself quickly. The terrain is too vertical, the towns too remote, the experiences too deeply tied to weather, light, and access. This is a landscape that rewards travelers who arrive with curiosity and stay long enough to feel the rhythm of the place.
It is also a landscape best appreciated with the right guides, the right vehicles, and the right base of operations.
Travel into one of Mexico’s most extraordinary corners
A Closer Look Tours’ upcoming Copper Canyon journey is built around the very best of this remarkable region: rim-edge hotels with views thousands of feet down, the legendary El Chepe train ride through tunnels and bridges, encounters with the Rarámuri people who call these canyons home, and the kind of slow, immersive travel that turns a destination into a memory you carry for life.
