One Of The Largest Canyons In The World (And You've Probably Never Heard Of It)
The Fish River Canyon is Namibia's Grand Canyon. The canyon is only slightly smaller than the famous U.S. National Park, yet it still manages to fall off of foreign tourists' radar when researching their trip to Southern Africa. The canyon first developed with tectonic plate movement millions of years ago. Over time, wind erosion combined with the water of the Fish River carved an enormous gash in the earth which now measures approximately 160 km long and up to 27 km wide in sections.
It's an awesome site to see at sunset when the canyon walls are illuminated to a fiery orange color by the sun's rays. There is the option to book a hike through the canyon from mid-April through September. It's a 4-day long, 85km trail, so you should be reasonably fit before signing up.
