Located slightly off the main safari route, Tarangire National Park is a lovely, quiet park in Northern Tanzania. It is most famous for its elephant migration, birding and authentic safari atmosphere.
Tarangire is the surprise package on the Northern circuit. Often overshadowed by the Serengeti and the Ngorongoro Crater, Tarangire has huge concentrations of animals in the peak months and a fraction of the visitor numbers of any of the other Northern parks. From July through to October safaris are superb, and the atmosphere and habitats are completely different from other parks.
The best time to visit Tarangire is probably in the dry season from June - October, where the game viewing is at it's best. Tsatse flies tend to be pretty bad from December to March so although this is a good time to go to the Serengeti for the wildebeest calving, Tarangire is best avoided at this time.
