Ngorongoro crater is located in Ngorongoro Conservation Area Authority; a UNESCO protected World Heritage Site and an International Biosphere Reserve. Ngorongoro is the largest intact crater in the world and second largest extinct crater.    Ngorongoro was an active volcano some eight million years ago whose cone collapsed, leaving the huge crater  that is seen today. The Crater rim is wooded with mountain forest vegetation.  The crater has a spectacular concentration of wildlife.

Ngorongoro Conservation Area Authority has recently taken total control of one of its trail within the Northern Highland Forest Reserve (NHFR). (I am not sure this is of interest to most visitors.  I suggest you delete or elaborate with more explanation.)

Ngorongoro Crater can be reached by road from Arusha to Lodoare Gate entrance, which is 160 km long. It takes 3-4 hours to reach Ngorongoro Crater National Park from Arusha.

After completing the necessary registration at Loduare gate, you will go down into the Ngorongoro Crater for  a tour where you will see black rhino, elephant, leopards, buffalo, lion prides in the grasslands, hyenas, and  jackals, as well as large herds of zebras and wildebeests.
