The Central Kalahari Game Reserve (CKGR) is the world's second-largest game reserve, sprawling across 52,800 km² (larger than the Netherlands) in the heart of Botswana's semi-arid Kalahari Desert. Established in 1961, it's a UNESCO tentative World Heritage site famed for its vast fossil pans, ancient river valleys, rolling sand dunes, and golden grasslands – a stark, timeless wilderness where desert-adapted wildlife thrives amid extreme isolation. Home to the San (Bushmen) for millennia, CKGR symbolizes resilience, with ongoing community conservation efforts despite historical relocation debates.
