Nxai Pan is a large salt pan topographic depression which is part of the larger Makgadikgadi Pans in northeastern Botswana. It lies on the old Pandamatenga Trail, which until the 1960s was used for overland cattle drives. The area is speckled with umbrella acacias and is said to resemble the Serengeti in Tanzania. This landform is a major part of the Nxai pan, and is a seasonal home to large herds of zebra and wildebeest. In the rainy season between December and April the pan becomes grassy and attracts these animals in their tens of thousands, along with smaller numbers of gemsbok, eland and red hartebeest.
