Lake Manyara National Park.

Tucked beneath the dramatic wall of the Great Rift Valley escarpment, Lake Manyara National Park pairs a shallow soda lake with dense groundwater forest and open acacia woodland. The park is famous for its unusual tree-climbing lions, lounging in the branches of acacia and fig trees, and for the vast flocks of flamingos and pelicans that gather along the lake's alkaline shallows. A rich population of elephant, buffalo, and giraffe moves through the forest, making Manyara a compact but rewarding stop on the northern circuit.
