Kasanka National Park
Kasanka National Park is a park located in the Serenje District of Zambia’s Central Province. At roughly 390km2, Kasanka is one of Zambia’s smallest national parks. Kasanka’s situation is interesting as it is the first of Zambia’s national parks to be privately managed. The privately funded Kasanka Trust Ltd has taken on all management responsibilities, in partnership with the Zambian Wildlife Authority, and has been in operation since 1986.
