The best time to visit Tarangire, and why the elephants decide it

The months when the river concentrates everything.

The best time to visit Tarangire is decided by water. For about five months of the year the Tarangire River and the swamps it feeds are the only dependable drinking water across a large part of the Maasai Steppe, and the elephants, buffalo, zebra and wildebeest that spent the rains scattered over community land walk back in to use it. When the rain returns, most of them walk out again.

So the same park gives two very different days, depending on the month. This guide goes through the year as we plan it from Arusha: when the herds build, when they thin, what the wet months are good for, and how many nights the park deserves. The practical detail on gates and where to sleep is on our Tarangire National Park page.

The short answer

The best time to visit Tarangire is the dry season, June to October, when the Tarangire River is the main water for a very wide area and elephants gather along it in large herds. August to October is the peak. From November to May many animals leave the park, and April and May are the wettest months.

Why the Tarangire River decides the best time to visit

Tarangire National Park covers about 2,850 square kilometres, but the animals that use it range over an area several times that size. The park has no fence. Researchers who have followed its elephants since the 1990s describe a simple pattern: in the wet season most of the large grazers and browsers, elephants included, move out to dispersal areas on the plains beyond the boundary, and they come back when the temporary water out there dries up.

What they come back to is the Tarangire River, which runs north through the park, and the swamps linked to it, of which Silale is the best known. The river often shrinks to pools and damp sand by September. Elephants dig into the sand for the water underneath, and other animals wait their turn at the holes. That is why the dry-season drives follow the river so closely.

On numbers, be careful with any single figure. The Tanzania National Parks authority describes the park as holding more than 3,000 elephants. The long-running study of one identified group, published in the journal Oryx in 2010, counted it growing from 226 animals to 498 between 1993 and 2005, close to the fastest growth elephants are capable of. Both point the same way: a large and recovering population that is most visible in the dry months.

June to October: Tarangire in the dry season

The long rains usually end in May, and through June the country around the park dries from the outside in. June still has tall grass and some green, with cool mornings and few vehicles. The herds are arriving but not yet packed along the river. If you like a quieter park and do not need the spectacle at full strength, June and early July are good months.

August, September and October are the peak. The grass is short or gone, the baobabs are bare, and you can see a long way through the bush. Elephant families come down to the river through the day, often several groups at once, with buffalo, zebra, wildebeest and giraffe using the same stretches and lions never far from the water. Our own month ratings mark September as Tarangire at its best.

The trade-offs are heat, dust and company. October afternoons are hot, the tracks are powdery, and the gate can queue in mid-morning when the day visitors from Arusha arrive together. Tsetse flies live in the wooded parts of the park in every season; wear light, neutral colours and avoid dark blue and black, which attract them. They are a nuisance, not a reason to stay away.

November to May: Tarangire in the wet season

The short rains usually begin in November, and the effect on the animals is quick. Once there is standing water and new grass outside the park, the wildebeest and zebra leave for the Simanjiro plains to the east and the country north towards Lake Natron, and many of the elephants follow. Tarangire does not empty. There are resident elephants, giraffe, impala and lions all year, but you will work harder for them and the grass hides a good deal.

What you get in exchange is a green park with very few vehicles, clear air, storms building over the baobabs, and birds. Around 550 species have been recorded here, and from November to April the migrants from Europe and Asia are present, which is why our Birding the North plan includes Tarangire in those months. January and February often bring a drier spell between the two rains.

April and May are the months we would steer you away from unless the price matters most. April is usually the wettest month, the black cotton soil in the south turns to mud, and some camps close until June. A day in the park is still possible and can be pleasant between showers. It is simply not the Tarangire people describe when they come home.

How many days in Tarangire, and where to spend them

Tarangire is about 121 kilometres from Arusha, roughly two hours on tarmac, which is why it works as a day trip. Our Tarangire day trip from Arusha gives you five hours or more in the northern part of the park, along the river, and in the dry season that is where most of the animals are. You leave before the evening light, and you do not reach the south.

One night changes the day more than you might expect. Sleeping inside the park, or close to the gate, puts you on the river in the first hour of light, before the day traffic, and again in the late afternoon. The gates close at six in the evening, so a day visitor is already on the road home when the light is at its best.

Two nights let you spend a full day in the south, around the Silale swamp, with a packed lunch. The swamp holds water and green grazing long after the rest has dried, and far fewer vehicles get that far. If elephants are the reason you are coming to Tanzania, two nights here in September will give you more of them than a week anywhere else in the north.

Fitting Tarangire into a northern circuit safari

On most itineraries Tarangire is the first park, because it is the nearest to Arusha and lies on the road to Lake Manyara and the Ngorongoro highlands. The three-day Tarangire, Ngorongoro and Manyara plan starts here, and so does the seven-day Great Midrange Journey, which carries on to the Serengeti. In the dry season we would give Tarangire a night of its own on either.

The dry season here is also the season of the river crossings in the northern Serengeti, so July to October is the busiest and most expensive time across the north. Camps inside Tarangire are few and fill early for August and September. If your dates fall between November and March, Tarangire still earns a day, but put the extra nights elsewhere; the migration calendar shows where the Serengeti herds are in those months.

One decision is made when the beds are chosen. Walking and night drives are run mainly on the community wildlife areas along the park boundary, and less commonly inside it, so if either matters to you, say so at the start. We explain the rules in what changes after dark. Park fees are set by the authority and change; we itemise them on every quote.

Questions people ask

September, closely followed by August and October. By then the land outside the park is dry, the grass is short and the elephants are gathered along the Tarangire River and the swamps. June and July are quieter and still good. April and May are the wettest and least rewarding months.

The Tanzania National Parks authority describes Tarangire as home to more than 3,000 elephants. The number inside the park changes with the season, because many of them spend the rains on the plains outside the boundary and return to the river from about June.

Yes, with the right expectations. From November to March the park is green and quiet, the birding is at its best and there are still resident elephants, giraffe and lions. You will see fewer animals than in the dry season, and April and May can be very wet.

Yes. The park is about two hours from Arusha on tarmac, and a full day gives five hours or more along the river in the north of the park. You miss the early morning, the evening light and the southern swamps, which is the case for staying a night.

One full day shows you the river and the northern part of the park. One night adds the first and last hours of light. Two nights let you reach the Silale swamp in the south, which most visitors never see. In the dry season we suggest at least one night.

Yes, in the wooded parts of the park, in every season. Their bite is sharp but for most visitors they are a nuisance only. Wear light, neutral colours, avoid dark blue and black, use repellent, and ask your guide to close the roof in the worst stretches.

For elephants in the dry season, yes. Tarangire has the largest elephant population in northern Tanzania and the river draws the herds together. The Serengeti is far larger and better for big cats and the wildebeest migration. Most northern itineraries include both.
