The Nxai Pan in Botswana may have developed around five million years ago.
The Botswana landscape's vast sky and horizon constantly impresses visitors.
Nxai Pan, again part of the former lake bed, is a large grass plain with numerous acacia trees.
This 1676-square-kilometer game reserve was expanded to include Baines Baobabs in 1992, making it 2578 square kilometres.
Nxai Pan National Park is a saltpan. A good rain fills the pan and grasslands.
All-wheel-drive vehicles should enter the pan. Park campsites are two.
The wet season brings vast herds to Nxai's grassy pans, making this one of Botswana's most intriguing places.
