Okavango Delta, Botswana

It seems a bit weird that a river doesn’t reach the sea, but this is what happens to the Okavango, the fourth longest river on the African continent. It rises on the Angolan mountains to finish his race in Botswana, flowing into a sandy sea: the Kalahari desert.

The origin of this phenomenon dates back to the ice age, when the river flowed into the great Makgadikgadi lake, now a desert.

At its mouth, it forms an internal delta, a cradle of unbelievable biodiversity considered one of the best-preserved natural areas where huge quantities of animals can be found, of almost all the species of the African continent.
