Northern Tanzania gets the visitors; the south gets the space. Nyerere National Park and Ruaha are both enormous, both far less crowded, and both allow activities the northern parks do not.
Nyerere National Park
Carved in 2019 out of the northern part of the Selous Game Reserve, Nyerere covers 30,893 square kilometres, making it one of the largest national parks in Africa. Its centre is the Rufiji River and a chain of lakes, which allows boat safaris — the single best reason to come. Drifting past hippo pods, crocodiles on sandbanks and elephants drinking at the edge is a different experience from a vehicle. Walking safaris with an armed ranger are also permitted.
Wildlife and the poaching record
The Selous held around 110,000 elephants in the 1970s and fell to roughly 15,000 by 2014, one of the worst poaching collapses recorded anywhere. Numbers have since stabilised and are slowly rising. The ecosystem holds large populations of buffalo, hippo, crocodile, giraffe and one of the most important remaining populations of African wild dog. Lions are numerous but less habituated than in the north.
The dam
The Julius Nyerere hydropower project on the Rufiji, inside the World Heritage site, was completed in 2024 and flooded a substantial area. It remains contested by conservation bodies, and its long-term effect on the floodplain downstream is not yet clear. Visitors will encounter the reservoir; the tourism area along the northern lakes still functions.
Ruaha
Ruaha covers about 20,000 square kilometres in the centre of the country, where eastern and southern African species overlap: both greater and lesser kudu, sable and roan antelope, and around 10 percent of the world lion population. The Great Ruaha River is the focus in the dry season. Ruaha receives a few thousand visitors a year, against several hundred thousand for the Serengeti, and the difference is obvious the moment you arrive.
Getting there
Nyerere is a four to five hour drive or a 45 minute flight from Dar es Salaam, and there is now a passenger railway to Selous station. Ruaha is reached by flight from Dar or Arusha, or a long drive via Iringa. Most people fly; the roads are slow and become difficult in the rains.
Season
June to October is the dry season and the reliable time; many camps close entirely from March to May, when the rains make tracks impassable. The green season in January and February is possible in Nyerere and excellent for birds.
