It is the vast number of baobabs that first capture the eye as you enter Tarangire National Park.The Tarangire River has shrivelled to a shadow of its wet season self. But it is choked with wildlife. Thirsty nomads have wandered hundreds of parched kilometres knowing that here, always, there is water. Tarangire covers an area of 2,600 sq km (1,005 sq miles) and located 118 km (75 miles) southwest of Arusha.
Herds of up to 300 elephants scratch the dry river bed for underground streams, while migratory wildebeest, zebra, buffalo, impala, gazelle, hartebeest and eland crowd the shrinking lagoons. Tarangire’s mobs of elephant are easily encountered, wet or dry. The swamps, tinged green year round, are the focus for 550 bird varieties, the most breeding species in one habitat anywhere in the world.
June to October is the best time to see large number of wildebeest, elephants, zebras, and hartebeest. Not all animals are migratory though, other animals such as giraffes, Impala, Eland, lesser kudu, waterbuck, gazelle and sometimes rhinos or leopards can be seen throughout the year. More people are attracted by the giant pythons and large herds of elephants. the park is also famous for migrant birds.

They migrate to the park in search for water, which is provided by Tarangire River, and predators migrate along in search for preys. During this period the park has the largest concentration of animals than in any park in the northern Tanzania
