The Parks That Make Up the Southern Circuit
Nyerere National Park (formerly Selous Game Reserve) is the anchor of the south. It is one of the largest protected areas in Africa, and its defining feature is the Rufiji River—a broad, lazy waterway that draws hippos, crocodiles, and elephants to its banks. The park is best experienced from the water as much as from the vehicle. A boat safari here is not a side activity; it is the main event for many visitors, offering a perspective on wildlife you simply cannot get from a game drive.
Ruaha National Park is the other heavyweight. It is Tanzania's largest national park by a significant margin, larger than the Serengeti, yet it receives a fraction of the visitors. The Great Ruaha River bisects the park, creating dramatic gorges and concentrations of wildlife during the dry season. Ruaha is known for its elephants—some of the largest herds in East Africa—and for its lions, which live in large prides adapted to hunting buffalo. It is also one of the most reliable places in Africa to see African wild dogs, a species that has vanished from much of its former range.
Mikumi National Park is the accessible one. It sits a few hours' drive from Dar es Salaam, which makes it the easiest southern park to reach without internal flights. It is smaller and busier than Ruaha or Nyerere, but it delivers reliable wildlife viewing—elephants, lions, giraffes, zebras, and buffalo—and it works well for travelers with limited time or a tighter budget.
Udzungwa Mountains National Park is the wildcard. It is not a traditional game-drive park. It is a rainforest, often called the "Galápagos of Africa," home to primate species found nowhere else, including the Iringa red colobus and the Sanje crested mangabey. If you are a hiker or a birder, a day here adds a completely different dimension to a southern safari.
