Uganda biggest national park

Murchison Falls National Park

Murchison Falls is by far Uganda's largest national park, protecting a chunk of untamed African savannah bisected by the mighty river Nile. This vast national park (3840 sq km) is named for the dramatic Murchison Falls, where the world's longest river explodes violently through a narrow cleft in the Rift Valley escarpment to plunge into a frothing pool 43m below. Uganda Wildlife populations have largely recovered from the poaching of the 1980s. In the lush borassus grassland to the north of the Nile, elephant, buffalo, giraffe and a variety of antelope are regularly encountered on game drives, while lion are seen with increasing frequency. To the southeast, Rabongo Forest is home to chimps and other rainforest creatures. The Nile itself hosts one of Africa's densest hippo and crocodile populations, in addition to prolific bird life including the world’s most accessible and most sought after wild population of the rare shoebill stork.
