Ngorongoro National Park is best-known for its natural wonder, the crater. As the world’s largest unflooded and unbroken caldera, its 20km diameter span, and 600m slopes, it is no wonder why it is dubbed Africa’s “Garden of Eden.” The park preserves the black rhino in its plains, as well as other amazing animals found in the country. You cannot miss passing historical spots such as the Oldupai Gorge and visiting Lake Ndutu cradled in the crater.
