The old­est in the coun­try, as it received its sta­tus back in 1939. Sev­er­al rivers flow through it. Wet­lands and forests, form­ing a green cor­ri­dor, spread over an area of 23,000 km². This is an untouched cor­ner of the wild, in which African buf­faloes, white rhi­nos, giant for­est boars, lions, and pel­i­cans live com­fort­ably.
