It is partly adjacent to the Kenya border and is northwest of the adjoining Ngorongoro Conservation Area. It is best known for its huge herds of plains animals (especially gnu [wildebeests], gazelles, and zebras), and it is the only place in Africa where vast land-animal migrations still take place. The park, an international tourist attraction, was added to the UNESCO World Heritage List in 1981.
