An African safari in Botswana's Okavango Delta takes you to the largest inland delta in the world, and one of Africa’s most scenic and remarkable wilderness regions. Almost the entire Delta is a protected area. Each winter, floods pour down from the highlands of Angola into the Okavango River and flow on through a vast network of narrow waterways, lagoons and out over the floodplains until they are soaked up by the sands of the Kalahari Desert. A fraction of the water may remain to flood lakes further south and eventually to end in the huge depression of the Makgadikgadi Pan. The floods reach their peak some time between May and August and then gradually subside. This continual change in water levels gives rise to a remarkable variety of habitats and landscapes makingfor a very varied African safari. There are permanent water channels, lined with thick papyrus, seasonally flooded grass plains with islands of palm trees and dense vegetation, and some areas of higher ground with mopane forests and permanent savannah.
