Here's an amazing drone's eye view of Namibia's famed Fish River Canyon, compliments of contributor XG121. Located in the southern part of the country near the South African border, it's created by the Fish River. The canyon is about 160 km (around 100 mi.) long, and up to 550 meters (around 1.8k ft.) deep. It's the largest canyon on the African continent, and appears near the top of most authoritative lists of the world's top canyons. Its accessible via a hiking trail, one of the most popular in Sub-Saharan Africa.
