Tanzania offers good wildlife viewing throughout the year. There are three different safari circuits, and each one of them alone would make Tanzania a great wildlife destination. The Big Five and most other high profile animals are easily seen. The black rhino is very rare throughout, with the exception of the Ngorongoro Crater where a small resident population is often spotted. The best chance for seeing the wildebeest migration is during June and July and the time to see the wildebeest calving in the Serengeti is late January to February. The Dry season (late June to October) is generally the best time for wildlife viewing throughout. At this time, the bush is less dense, and animals tend to congregate around waterholes. The Wet season (November-May) is often more beautiful when the parks are green, and tourist numbers are lower. The parks in the Southern and Western circuit are less accessible in the long rains (March to May) and some lodges close in that period.You’ll have few problems spotting the more-prominent African animals in Tanzania, including the lion, elephant, giraffe and buffalo. For big cats like the leopard and cheetah, you’ll want to head to the Serengeti, while Ngorongoro Crater is where you want to be for a chance of seeing a black rhino. Other wildlife highlights include chimpanzee tracking, checking out African wild dogs, and being awestruck by the several million wildebeest, gazelle and zebra on their annual migration.
