Geographical location and geology
The Ngorongoro Crater is located about 180 kilometers west of Arusha, a 3–4 hour drive on a well-developed road via Karatu. It is part of the Ngorongoro Conservation Area (NCA), a UNESCO World Heritage Site since 1979 and a multi-purpose protected area of 8,300 square kilometers – separated from the original Serengeti National Park in 1959 to preserve the Maasai’s traditional grazing rights.
Geologically, the crater is a caldera: the collapsed summit of a volcano that erupted 2 to 3 million years ago and then collapsed. With an area of 260 km², a diameter of 20 km, and a depth of 610 metres, it is the largest intact, unflooded volcanic caldera on earth. The crater floor is at 1,800 metres – the rim at around 2,300 to 2,400 metres. The temperature difference between the ground and the edge is 5 to 10 degrees Celsius, depending on the time of day.
The protected area encompasses much more than the crater: Empakaai Crater, Olmoti Crater, Olduvai Gorge, Ndutu Plains, and wide short grass plains where part of the Serengeti migration runs. The NCA is the ecologically and culturally most complex protected area in northern Tanzania.
What makes the Ngorongoro Crater unique
- Africa’s highest concentration of wild animals in a limited area: 25,000–30,000 large mammals live on the crater floor all year round – naturally enclosed by 610-metre-high walls. No artificial fencing, no game reserve. A natural arena that has worked like this for millions of years.
- Big Five reliable all year round: In contrast to the Serengeti, where animals undertake long seasonal migrations, lions, elephants, buffaloes, leopards and black rhinoceroses remain on the crater floor all year round. No other destination in Africa offers the Big Five with this predictability.
- Wild black rhinos: The rhino population of the crater is wild and free – not in a protected enclosure like in Mkomazi. The crater floor is thus one of only two places in Tanzania with reliable rhino observation.
- No giraffes, no impalas: Two of Africa’s most common savannah animals are completely absent from the crater floor. The reason: The 610-meter-high steep walls are anatomically insurmountable for giraffes, and impalas follow their evasive behavior. This absence is not a defect – it is evidence of natural containment.
- Highest lion density in Africa: The crater floor is considered the area with the densest known lion population on the continent. Early in the morning, when the animals are still active after the night hunt (6–9 a.m.), sightings are almost guaranteed.
- Tanzania’s only multi-use protected area: The Maasai are allowed to graze their cattle on the plateaus and sometimes on the crater floor. This coexistence of wild animals and semi-nomads is unique and was recognized as a World Heritage Site by UNESCO in 1979.
- Olduvai Gorge – 45 kilometres away: The most palaeoanthropologically important site in human history is located directly on the way to the Serengeti. No other safari stop in northern Tanzania allows the combination of a Big Five safari and 3.6 million years of human history in one day.
The Big Five – and what distinguishes the crater from any other park
On an area smaller than Lake Manyara, smaller than Tarangire, many times smaller than the Serengeti, 25,000 to 30,000 large mammals live permanently. Lions hunt within sight of the vehicles. Herds of buffalo drink at the permanent watering holes. Bull elephants stroll through the Lerai fever forest. And on the edge of Lake Magadi, usually in the morning between 7 and 10 a.m., the outlines of the rare black rhinos appear – the most elusive of the Big Five, visible here like nowhere else in the wild.
Best predator viewing time: 6–9 a.m. after night; Lions still active, light good, grass short (dry season). Ngoitokitok headwaters southeast of Lake Magadi: permanent hippo pool, reliable at any time of the day.
Lake Magadi – Pink in the Crater Heart
At the center of the crater floor is the alkaline Lake Magadi, fed by the Munge River. In the rainy season and afterwards, thousands of flamingos cavort on the shore – their pink in front of the dark basalt rock of the crater floor is photographically one of the strongest compositions in the entire northern district.
The largest herds of buffalo in the crater, the main hippo groups and the best bird watching are concentrated around the lake. The Ngoitokitok headwaters on the southeastern shore of the lake offer a permanent freshwater pool with reliable hippo sightings – all year round, at any time of the day.
Lerai Fever Forest – Elephants and Leopards
On the southern edge of the crater floor lies the Lerai Fever Forest – a dense strip of yellow-green acacia trees that bull elephants use as a retreat. This is where elephants show their most relaxed social behaviour: slow movements, young animals playing, old bulls patiently eating. The dense forest allows for close encounters that are not possible in the open savannah.
The Lerai Forest is also one of the crater’s most reliable leopard spots. The cats use the dense branches for sleeping and as an elevated hunting post – best visible early in the morning and in the evening hours.
Olduvai Gorge – The Cradle of Humankind
45 kilometers northwest of the crater, on the direct route to the Serengeti, lies the Olduvai Gorge – 14 to 90 meters deep, 48 kilometers long. Here, from 1931 onwards, Louis and Mary Leakey discovered fossils and stone tools that fundamentally changed the picture of human evolution. The most famous find: the Laetoli footprints, 3.6-million-year-old footprints of upright walking ancestors of Homo sapiens – the oldest known human footprints in the world.
- Logistics: Museum at the edge of the gorge; guided tours along the escarpment; Duration of visit approx. 45–90 minutes; on the direct route between Ngorongoro and Serengeti – no detour necessary.
Empakaai Crater – The Silent Antithesis
If you know the Ngorongoro Crater and want more, The Empakaai Crater is about a two-hour drive northeast of the main crater and is two-thirds covered by a deep blue, alkaline lake. 6 km in diameter, 300 meters deep – significantly smaller than Ngorongoro, but ecologically no less intense.
The descent to Empakaai is a guided walking safari – one of the few opportunities in the entire NCA conservation area to experience the forest on foot. Flamingos, buffaloes, the occasional rhino, and – on a clear day – the view of Ol Doinyo Lengai on the horizon make Empakaai the strongest hidden gem of the Ngorongoro Conservation Area.
- Combination: Empakaai + Olmoti Crater (walking safari, 2 hours ascent) + Lake Natron (descent into the Rift Valley) = one of the most impressive 3-day treks in northern Tanzania.
Maasai Coexistence – the only protected area of its kind
The Ngorongoro Conservation Area is the only protected area in Tanzania where a human community coexists with wildlife on an equal footing. The Maasai communities, who live in the highlands around the crater, are allowed to graze their cattle on the plateaus and at times on the crater floor itself – a regulation that has been in place since the founding of the NCA in 1959 and was explicitly recognized as a World Heritage Site by UNESCO in 1979.

Ideal length of stay
- 1 day (day trip): possible from Arusha or Karatu. Crater floor 6 a.m.–12 p.m.; Permit for a descent. All Big Five realistic – but no Empakaai, no Olduvai, no sunset crater view from the rim.
- 2 nights (recommended): Day 1: Arrival, afternoon crater rim walk, sunset; Day 2: Early morning descent (6 am), full game drive; Olduvai on the way to or from the Serengeti. Optimal price-experience ratio.
- 3-4 nights (NCA focus): Empakaai Crater, Olmoti Crater, Walking Safari, Maasai Boma Visit, second crater floor day without time pressure. For birdwatchers, photographers, culture enthusiasts.
- 5+ nights (complete sanctuary): Additionally, Lake Eyasi (Hadzabe Bushmen), Lake Natron / Ol Doinyo Lengai, Ndutu Plains (calving season Jan.–Feb.). The most complete NCA exploration possible.
Travel times: concrete assessment
Period | Conditions | Recommendation |
June – October | Dry season; short grass; animals concentrated at watering holes; clear vision; cool (15–19°C ground, below 10°C at night at the edge); Lions active; rhinos clearly visible; Highest number of visitors | Best wildlife viewing – but full |
Nov. – Dec. | Short rainy season; crater floor bright green; Migratory birds from Europe; flamingos at Lake Magadi; significantly fewer vehicles; Prices cheaper | Very good for birds + photographers; more peace |
Jan. – Feb. | intermediate drying season; Vegetation still green; lowest number of visitors; at the same time wildebeest calving on Ndutu plains (45 min. west) – ideal combination | Insider tip – quietest, most versatile time |
March – May | main rainy season; dense grass; occasional road problems on gravel roads; Crater floor accessible all year round; Lodge price reductions; almost no other tourists | For the determined: pure exclusivity |
Principle: The Ngorongoro Crater is first-class all year round, because the animals are always there. The question is not “When are there animals?”, but “How many other tourists are there, and what does the landscape look like?” January to February is the best answer to both questions: few tourists, green landscape, and at the same time wildebeest calving on the nearby Ndutu plains.
Conclusion
The Ngorongoro Crater is the structurally strongest single destination of the northern Tanzanian safari system: year-round, reliable, geologically unique, and ecologically unparalleled. No other park on earth offers the Big Five with such predictability in such a limited space – and no other place combines Big Five safari, wild black rhinos, and 3.6 million years of human history in one day trip.
Two nights is the minimum for a full experience. The entire protected area opens for three nights. If you are on the crater floor early enough – west descent from 6 a.m., east descent (Lemala Gate) even earlier – experience the crater before the day visitors arrive. This is the only time advantage that overnight guests in the Ngorongoro have over day tourists – and it is significant.
