The Okavango located on the Kalahari is a huge delta of the Okavango River. It's what's called an endorheic basin and experiences water loss through evaporation as well as transpiration that takes place through the verdant foliage as the delta is carpeted with lush vegetation and is a verdant swampland that's home to a variety of wildlife including amphibians, birds, reptiles and fish. The Okavango is a designated UNESCO World Heritage Site and is also on the list of Africa's seven wonders. It's therefore, well worth the effort to ask your Botswana hotel about planning an excursion to the area.
