Hwange National Park is the largest wildlife reserve in Zimbabwe, occupying roughly 14,650 sq. km. It is in the northwest corner of the country, about one hour south of Victoria Falls by air, and is distinctive by its deep Kalahari sands which blew across the continent aeons ago and now support ancient hardwood forests, savannah grasslands and acacia trees. Visitors to Hwange are guaranteed to see an incredible range of wildlife, with over 100 species of mammals and nearly 400 bird species recorded. The elephants of Hwange are world famous and the park's elephant population is one of the largest in the world, the last estimate being 44,000 from a recent aerial survey.
