The Ngorongoro Conservation Area was officially declared a UNESCO world heritage site in 1979. The area consists of various landscapes and includes dense mountain forests, woodlands, grasslands, lakes and swamps. Some of the most important archeological sites in the world, such as Oldupai Gorge and Laetoli can be found in the Ngorongoro Conservation Area. Archeologists found evidence showing that the area was occupied by hominids over 3 million years ago and thus claiming that it could be the birthplace of mankind.
