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.
And then of course there is the Ngorongoro Crater, the largest unbroken, inactive and unfilled caldera in the world. With a diameter of approximately 19 km (12 miles) and its majestic walls that rise just over 610 m (2000 feet), the crater floor covers an area of 260 sq km (100 sq miles). Over 30,000 animals including the rare black rhino call this unique place their home. Today over 40,000 Masais reside in the area making the Ngorongoro Conservation Area one of the only places in Tanzania where human habitation is allowed within a wildlife protected area. The conservation shares a boundary with the Serengeti National Park and one must drive through the conservation in order to get to the Serengeti
