Search for a Tanzania safari and you will be offered the same week in a dozen arrangements: Tarangire, the Ngorongoro Crater, the Serengeti, back to Arusha. It is the northern circuit, it is genuinely extraordinary, and it is also the only part of the country most itineraries acknowledge.
That is not a conspiracy. The northern parks sit close together, the roads between them are the best in the country, and one airport serves all of them. A first trip that goes nowhere else is a perfectly good trip. But it is worth knowing what the other three parts of Tanzania are, because they answer different questions — and if the northern circuit is not what you actually wanted, nothing about it will tell you so.
The south is bigger, hotter and emptier
Two parks dominate it. Nyerere National Park was gazetted in 2019 out of the northern sector of the Selous Game Reserve, and almost everything that made Selous famous as a photographic destination is inside the new park rather than the reserve that kept the old name. TANAPA describes it as Africa’s largest national park and gives its area as 30,893 square kilometres. Its published elevation range is 100 to 400 metres and its temperature range 13 to 41 degrees — which is a fair warning as much as a statistic. This is low, hot country.
The Rufiji runs through it, and the boat is the point. Game viewing from the water is a different activity from game viewing from a vehicle: you approach from an angle animals are not watching, and the river itself is the attraction.
Ruaha is the other one, and it is the country’s second largest national park, not the largest — a distinction that predates Nyerere’s gazettal and is still got wrong constantly. TANAPA gives it about 19,822 square kilometres after boundary changes in 2023. Walking is available in designated zones with an authorised ranger, which means it is arranged in advance rather than decided over breakfast.
Between them and the coast sits Mikumi, which is the one southern park you can reach on a surfaced road from Dar es Salaam, and is often used as a short introduction rather than a destination in its own right.
The west is about chimpanzees, and it is far
Mahale and Gombe sit on the shore of Lake Tanganyika, and neither is somewhere you arrive by accident. Mahale holds the largest chimpanzee population of any Tanzanian national park. Gombe is the smallest national park in the country and the one where Jane Goodall began the study that changed what was known about the species.
Getting there is the constraint, not the parks. Neither is on the way to anything, and adding them to a northern trip means flights rather than a longer drive.
And one park you cannot drive around at all
Udzungwa Mountains National Park is the only national park in Tanzania with no game-drive circuit. You walk, or you do not go. It is a forest and mountain destination rather than a plains one, and it rewards a completely different kind of visitor.
How to use this
The honest summary is that these are not rankings. The northern circuit concentrates famous animals in accessible places; the south trades that density for space and heat; the west trades both for chimpanzees; Udzungwa is not a safari at all.
What decides it is usually time and tolerance for flying, which is covered in more detail in how many days you need and getting around Tanzania. If you have a week, the northern circuit exists for a reason. If you have two, the question is worth asking properly.
Operators listing trips on this site publish their own itineraries across all four, and you can compare what each one covers rather than take a recommendation on trust.
