Grand Canyon, eat your heart out… there’s nothing on earth quite like Namibia’s Fish River Canyon. Taking geography to the extreme, the canyon measures a staggering 160km in length, 27kms wide and reaches a dramatic 550 m depth in the inner canyon. At the base, the Fish River itself winds a serpentine route through crumbling rocks, plunging gullies and ancient chasms. It’s no exaggeration to say that this is possibly some of the harshest terrain on the continent and hiking is demanding yet mind-blowingly rewarding. Forming part of the Ai-Ais National Park, a trans-frontier conservation area that’s home to klipspringer, zebra and a multitude of baboons, this is a canyon that’s like no other.
