If you are coming to Tanzania in July, August, September, October — and most people do — you will likely be told to spend three days in the Serengeti, one night at the Ngorongoro rim, one night at Manyara, and to consider Tarangire optional on the way back to Arusha. We push hard the other way. Tarangire’s schedule is the exact reverse of the Serengeti’s. The dry season that scatters animals across the great northern parks is the season that concentrates them here. Two days in Tarangire in August can be as productive as four days further north — and considerably less crowded.
The reason is the river. Tarangire National Park sits inside an ecosystem thirteen times its size, and through the wet months — December through May — the migrating herds spread out across that wider landscape, pushing east into the Maasai Steppe to feed on phosphorus-rich grasses the park itself doesn’t grow. Then in June the outlying areas dry out. Water sources disappear. The only permanent river in the region is the Tarangire, and the herds come back. By August every elephant, buffalo, zebra and wildebeest within fifty miles is inside the park boundary.
Tarangire’s rhythm is the opposite of the Serengeti’s. The months that empty the Serengeti are the months that fill Tarangire to the brim.
The elephant baby boom.
The famous part is the elephants. Heavily poached through the 1980s, Tarangire’s elephant population was counted at roughly three thousand by the year 2000. It has continued to climb since — we do not have a current official number, but the visual evidence is everywhere. Walk through any larger herd and a quarter of the animals you see will be under ten years old. Calves nursing. Adolescents playing. Matriarchs the size of small trucks. Tarangire is the easiest place in northern Tanzania to grasp the social complexity of an elephant family in real time.
The baobabs, and what lives in them.
The other postcard feature is the baobab. They are everywhere — the upside-down trees, hollow-trunked, sometimes hundreds of years old, surviving the dry by storing water in their fibrous interiors. They are also condominium blocks. Honeybees live inside the trunks. Bushbabies sleep in the cavities. Leopards drape along the upper limbs. Genets, hornbills, oxpeckers, the lot. Driving slowly past a single big baobab and looking up will sometimes show you more species than half an hour of dedicated game-driving on the plains.
The green season’s secret.
If your dates fall in the green season (December through May) and the standard advice has you skipping Tarangire, push back. The migratory animals are not here, but the park’s scenery in those months is unbeatable: low light, lush grass, the baobabs against thunderclouds, very few vehicles in sight. The resident elephants are still inside, plus giraffe, impala, dik-dik, waterbuck, and the most diverse raptor population of any park in East Africa.
