Part of the Makgadikgadi complex, Nxai Pan NP comprises several large pans. Nxai Pan is the easiest of the pans to drive to, and the wildlife viewing tends to be the best as well. Unlike the salt-encrusted pans at Makgadikgadi, Nxai Pan is a waterless, fossil pan covered in grass with acacia islands. The area comes to life after the summer rains in December, when big herds of migrating zebra and wildebeest, accompanied by other grazers, arrive to feast on the new grasses.
Make sure you avoid drinking tap water in Botswana. In urban areas the water is chlorinated and local people may drink it, however we very strongly advise you drink bottled water at all times. Water outside of the urban areas is contaminated. ... The water in Botswana is not safe to drink.
Nxai Pan can be visited year-round. It’s a seasonal park and wildlife migrates to the park in the wet, summer months – but the exact timing is erratic and depends on rainfall. Little wildlife is left in the dry months, from June to September.
