Serengeti National Park, national park and wildlife refuge on the Serengeti Plain in north-central Tanzania. 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.
The park was established in 1951 and covers 5,700 square miles (14,763 square km) of some of the best grassland range in Africa.Within the area are nearly 1,300,000 gnu, 60,000 zebras, 150,000 gazelles, and numerous other animals.
