The Okavango is a unique ecosystem of papyrus-lined waterways, knee-deep floodplains, water-lily lagoons, shady forest glades and rich savannah grasslands. All this fecundity lies in the middle of the largest continuous stretch of sand in the world - the Kalahari Desert Basin. Seen from space as an emerald swirl surrounded by a parched landscape, the Okavango Delta is an incredible source of life in a country that is 80% arid.
The Luangwa Valley covers almost the entire eastern region of Zambia and contains some sensational national parks. North Luangwa National Park is one of the most spectacular surviving wilderness areas in Africa and has been called "one of the greatest wildlife sanctuaries in the world today." It is so remote that self-drive safaris are not allowed and you may only enter if accompanied by a licensed guide. There is really only one main road leading there, but fly-in safaris make it accessible.
