Ruaha offers one of the largest populations of elephant in any African park, and the vast open areas are teeming with antelope and buffalo followed by the predators especially lion and potentially leopard, as well as African hunting dog and numerous giraffe and zebra. Historically, Ruaha was not a sought after destination for tourists due to the arid environment and the tsetse fly population; however, nowadays, the tsetse flies are under control and wildlife abounds. The best part is that it is still an uncrowded and undiscovered reserve.
Ruaha National Park has a high diversity of plants and animals; including elephants, buffalos, antelopes and some of rare and endangered species like the African wild dog. There is a considerable population of crocodiles and other reptiles; such as snakes and monitor lizards. Natural springs occur throughout the park, which act as dry season refuges for wildlife in search of water. There are only a few safari lodges in Ruaha National Park, all of which offer drives, while some offer guided walks as well as fly camping, which are exciting activities appealing to the more adventurous guest.
Ruaha National Park is an unspoiled wilderness famed for its large number of elephants. In fact, aside from rhinos, most major safari animals are easily seen here. Large prides of lion, sometimes counting more than 20 individuals, roam the park and even buffalo, an unusual prey, isn't safe here. Ruaha’s flagship animal is the wild dog. There are only a handful of places where these charismatic pack animals are easily observed, and this is one of the best. Ruaha is also home to the largest population of greater kudu in East Africa. Other rare antelope species that can be seen here include lesser kudu, roan and sable antelope.
Ruaha National Park has an impressive checklist of over 450 birds. This great diversity of species is a function of Ruaha’s location, which is transitional to the acacia savannah of East Africa and the miombo woodland belt of southern Africa. Crested barbet, whose persistent trilling is a characteristic sound of the southern bush, occurs in Ruaha, alongside central Tanzanian endemics such as yellow-collared lovebird and ashy starling. Migratory birds are present from November to April. The birdlife in Ruaha is good year-round, but is at its best from November to April when Palearctic and intra-African migrants are present. At this time, many resident bird species are nesting and are in breeding plumage. For wildlife viewing, June to October (the middle and end of the Dry season), is best for visiting the park.
