After finding the flattest spots in the world, we thought we'd try the opposite. From climbing to hiking to paddling, these canyons deliver some of the world's best outdoor adventures.
Check out some of the deepest, most remote and most spectacular canyons in the world below.
Colca Canyon, Peru
With a depth of over 10,000 feet, Peru’s Colca Canyon is one of the deepest in the world and almost twice as deep as the Grand Canyon. It's so remote, that it wasn’t until a team of adventurers made the first descent of the river Colca 30 years ago that the depths were officially recognized.
Waimea Canyon, Hawaii
It may be better known for its surf breaks, but the natural wonders inland on Hawaii are just as daunting, intimidating — and awesome. This is the Waimea, the deepest canyon in the Pacific. Aloha!
Verdon Gorge, France
Situated in southern France, the Verdon Gorge is a stunning geological wonder, whose 1,300-foot vertical walls of limestone have been attracting climbers for decades. And more recently, highliners. Watch Mich Kemeter highline in the Verdon Gorge right here.
Fjaðrárgljúfur Canyon, Iceland
When it comes to difficult locations to pronounce, Iceland's place names take some beating. We’re not sure where to begin with the Fjaðrárgljúfur Canyon, so if you ever find yourself in Iceland and want to know directions, we suggest you point at a map before even trying.
Blyde River Canyon, South Africa
There are many geological wonders in South Africa, from stunning coastlines, to jaw-dropping mountain ranges and awesome rivers that carve their way through the epic landscape. The Blyde River Canyon can count itself among the finest. At over 15 miles long and 2,400 feet deep, it's one of the largest and, thanks to its lush foliage, it's also one of the greenest.
Fish River Canyon, Namibia
When adventurers are looking for dramatic locations, sooner or later they come to places like Namibia's Fish River Canyon. Spectacular, remote and wild, its daytime temperatures can reach 104 degrees Fahrenheit. It's where ultra-runner Ryan Sandes came to smash the 56-mile hiking trail in 6 hours 57 minutes, which normally takes hikers five days. Sandes is pretty handy when it comes to running records. Here's another one he smashed in South Africa. But for lesser mortals, you can still turn up in a car and the most physical activity you need to do is reach for a phone to grab a shot.
Itaimbezinho Canyon, Brazil
The Itaimbezinho is a canyon in the state of Rio Grande do Sul, Brazil, about 630 miles south of Rio de Janeiro. Part of a national park, it's one of Brazil's lesser-known gems and simply gorge-ous! Afterward, head to Porto Alegre for some urban adventures.
Grand Canyon, Arizona
When it comes to canyons, there is usually only one that springs to mind – with good reason. It'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. Adventurer Brendan Leonard was one of the lucky ones. Check out the photogallery of a climbing and rafting adventure.
Kali Gandaki Gorge, Nepal
It's home to the world's highest mountains so it's a fair bet that Nepal is also home to the world's most dramatic rivers and canyons, carved by glaciers and charging snow-melt from the mountains. Although not confirmed, the Kali Gandaki could be the world's deepest gorge, since it's towered over by the mighty 5-mile-high Annapurna peak on one side. Record breaker or not, it's still an incredible place to visit — and with the recent devastating earthquake, Nepal will need tourists more than ever.
Indus Gorge, India
The confluence of the Indus and Zanskar rivers in Ladakh, each one fed from a different glacier and a slightly different color, is one of those popular places on the trekking trail that has to be seen with your own eyes. Surrounded by mighty peaks, it's an awesome location.
