Stretching south of Maun like an endless sea is the 52 800 square kilometre Central Kalahari Game Reserve. It is one of the largest parks in the world and offers a variety of species not found in other parts of Botswana. Deception Valley has large herds of springbok as well as lion, brown hyena, bat-eared foxes, black-backed jackals, suricates (meerkats), hares, gemsbok, eland and springbok. Ostrich, kori bustard, sandgrouse, larks and pipits are some of the birds that occur. The area is at its best during the green season when there is a large migration of game to the pans, and the flowers are abundant. There are private concession areas outside the park, which offer more flexibility for photographers than the camps inside the park.
