Lake Manyara National Park

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.
