Situated within the splendor of the Kalahari Desert in northwest Botswana, this World Heritage site features one of the highest concentrations of rock art in the world. Its massive quartzite rock formations loom from ancient sand dunes to the east and a dry fossil lakebed to the west, with archaeological records showing signs of human habitation spanning 100,000 years. Debswana, a joint venture between The De Beers Group of Companies and the Government of Botswana, is the world's largest diamond producer. Its non-profit entity, The Diamond Trust, has invested around $1 million in Tsodilo Hills, a site that draws travelers and makes a significant contribution to the national economy. Beyond the hills, the Kalahari Desert is also known for its excellent game viewing, particularly within the Central Kalahari Game Reserve. Seek out springbok, herds of wildebeest, cheetah, and the Kalahari's famous black-maned lions.
