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.
Ngorongoro Conservation Area
Ngorongoro is one of the true wonders of Africa, a lost world of wildlife and singular beauty in the near-perfect crater of a long-extinct volcano. This is one of the most extraordinary places in northern Tanzania and should on no account be missed.
Serengeti National Park
Few people forget their first encounter with the Serengeti. Perhaps it's the view from Naabi Hill at the park's entrance, from where the grasslands appear to stretch to the ends of the earth. Or maybe it's a coalition of lions stalking across open plains, their manes catching the breeze. Or it could be wildebeest and zebra migrating in their millions, following the ancient rhythm of Africa's seasons. Whatever it is, welcome to one of the greatest wildlife-watching destinations on earth.
