A speedboat sails the Okavango Delta on a water safari camp organized from Eagle Island Camp by Orient Express, outside the Moremi Game Reserve in Botswana. There are rivers that die at sea, waterways that run for miles over land, fatter, increasing its flow, to release into the ocean. There are others that flow in lakes, in other rivers ... But there are other, very few, who defied the established just pouring water into the desert sands inland, disappearing, vanishing as if by magic. This is what happens to the Okavango River, 1,600 miles after birth. After sprouting in southwestern Angola (which has the name of Cubango), turns east, away from the sea, starting its journey along the border between South Africa and Namibia (then being known as and Okavango) to go to die to Botswana. Well away from the Atlantic and Indian Oceans, in the middle of the southern cone of the continent, creating the largest inland delta in the world. Is the Kalahari which hosts the river, especially in the months of July and August, shortly after entering Botswana to the north. The aerial image is sensational phenomenon: in half the prevailing aridity, pale and bright land, languages ??stained green water their journey south. It looks like a tree without branches whose roots move unsuccessfully to nowhere. Such is the size of the delta (16,000 square miles, slightly larger than the area of ??the province of Huesca) that would have to climb on a satellite to see this accurately, but the flight can be done in light aircraft from Maun helps to gain an great idea of ??what is happening there. The river moves perfectly ordered, channeled, forming a broad riverside to reach the height of Sepupa, where everything is messed up, it overflows. This is where begins the inner delta, where the river splits into a thousand and one different routes (more the higher the water level that year) creating a maze of islands, rivers, streams, rivulets, brooks ... tens of kilometers later vanish, disappear.
