The area of conservation is not a national park and thus does not depend on Tanapa. US$50 per day and per person (US$10 for 6-16 years), for which Must add US$200 by vehicle. The park entrance costs consequently US$150 per person for a couple, US$100 for a trio, etc the name of Ngorongoro comes from that of the warriors of the tribe formerly installed in the crater, Likorongoros (name deformed by the German colonists in Ngorongoro). Les Maasaïs, warlike people and conqueror, drove out Likorongoro which finally migrated towards the lake Eyasi. They always live there, in a very primitive way, without houses nor clothing and only of hunting and picking. Maasaïs call them from now on Mangatis, that is to say “the respected enemies”. This region extends on 8,300 km2, including 260 km2 for the crater itself (largest will caldera in the world still intact), and 890 km2 for the forest of the chain of the volcanos. Created in 1951, Serengeti was well beyond its current border, and excluded Maasaïs from the pastures of the large plains. A conflict burst in 1956 between the national parks and Maasaïs. The area of conservation of Ngorongoro was then founded in 1959, at the same time like nature reserve to protect an exceptional fauna, like academy for the gorge of Olduvai, where the Leakey husbands had just discovered skull of Australopithecus zinjanthropus, and like and protection land of welcome of Maasaïs, which are today approximately 40,000 in the region. Two naturalists, Grzimek (to pronounce [Jimek]), have much work for the offer of the conservation in the region. Michael (1934-1959) died after its plane had run up against a vulture during the turning of famous Serengeti shall not die. His/her Bernhardt pere continued, also creating the zoological Company of Frankfurt, and marking the policy of protection of nature of many wild regions of the world, until his death in 1987. A stele is drawn up in honour of its sons on the edge of the crater.
