At 19km wide and with a surface of 264 sq km, Ngorongoro is one of the largest unbroken calderas in the world that isn’t a lake. Its steep walls soar 400m to 610m and provide the setting for an incredible natural drama, as prey and predators graze and stalk their way around the open grasslands, swamps and acacia woodland on the crater floor. It's such an impressive sight that, other vehicles aside, you'll wonder whether you've descended into a wildlife paradise.

Lake Manyara National park is one of Tanzania’s smaller and most underrated parks. While it may lack the size and variety of other northern-circuit destinations (there's pretty much one main north–south route through the park), its vegetation is diverse, ranging from savannah to marsh to evergreen forest (11 ecosystems in all) and it supports one of the highest biomass densities of large mammals in the world. The chance to see elephant families moving through the forest or Lake Manyara's famous population of tree-climbing lions (although sighting them is becoming increasingly rare) are alone reason enough to come.

Welcome to one of Africa's most underrated parks. Thanks to its proximity to Serengeti National Park and Ngorongoro Crater, Tarangire National Park is usually assigned only a day visit as part of a larger northern-circuit itinerary. Yet it deserves much more, at least in the dry season (July to October). It's a place where elephants dot the plains like cattle, and where lion roars and zebra barks fill the night.
