Largest canyonsThe Yarlung Tsangpo Grand Canyon (or Tsangpo Canyon), along the Yarlung Tsangpo River in Tibet, is regarded by some as the deepest canyon in the world at 5,500 metres (18,000 ft). It is slightly longer than the Grand Canyon in the United States.
For example, Yarlung Tsangpo is the greatest on the list, and is found in Tibet and China. Second on the list is the Indus Gorge in Pakistan. The Kali Gandaki Gorge in Nepal ranks third. The Tiger Leaping Gorge in China and the Cotahuasi in Peru rank fourth and fifth on the list.

Here, the river forms one of the deepest canyons in North America, its walls rising as much as 8,200 feet (2,500 m) from river to rim – about half a mile (0.8 km) deeper than the Grand Canyon. The canyons upstream at Cedar Grove are also more than 5,000 feet (1,500 m) deep.
The Yarlung Zangbo Grand Canyon in Tibet, a region of southwestern China, was formed over millions of years by the Yarlung Zangbo River. This canyon is the deepest in the world—at some points extending more than 5,300 meters (17,490 feet) from top to bottom.
The Grand Canyon has been carved, over millions of years, as the Colorado River cuts through the Colorado Plateau. The Colorado Plateau is a large area that was elevated through tectonic uplift millions of years ago. Geologists debate the age of the canyon itself—it may be between 5 million and 70 million years old.
This is the largest (and most beautiful) canyon in EuropeIn the heart of the picturesque Provence region lies a wonder of nature, known the world over as the Verdon Gorge.
The Grand Canyon, USAIt's the grandest of them all, the most striking and, unfortunately, the most popular: Arizona's Grand Canyon. The waiting list to raft the Colorado river can be as long as 10 years.
Mexico's Copper Canyon is much bigger than you thinkThe combined length of the ravines makes Mexico's Copper Canyon a whopping four times larger than the Grand Canyon in the United States. In some places, it's even deeper than the Grand Canyon, with a depth of over 1 mile (1.6 km)!
The canyon didn't get its name from its depth, though. It was actually often referred to as Box Canyon or Snake River Canyon by early explorers. The name Hells Canyon is believed to come from the difficult and rugged journey through the terrain by boat.
The geologic history of the rocks of Hells Canyon begins 300 million years ago with an arc of volcanoes that emerged from the waters of the Pacific Ocean. Over million of years, the volcanoes subsided and limestone built up on the underwater platforms. The basins between them were filled with sedimentary rock.
Of course, it's massively deep, too. From the top of the Seven Devils Mountains to the deepest part of the Snake River, Hells Canyon is nearly 8,000 feet deep. That's almost 2,000 feet deeper than the famous Grand Canyon in Arizona.
