Ngorongoro Conservation Area is in northern Tanzania. It’s home to the vast, volcanic Ngorongoro Crater and “big 5” game (elephant, lion, leopard, buffalo, rhino). Huge herds of wildebeests and zebras traverse its plains during their annual migration. Livestock belonging to the semi-nomadic Maasai tribe graze alongside wild animals. Hominin fossils found within the Olduvai Gorge go back many years.
