The Ngorongoro Crater is a huge volcanic caldera in northern Tanzania, about 260 square kilometres across and around 600 metres deep. Its walls hold in a permanent world of grassland, swamp, forest and a soda lake, and a large population of animals that rarely need to leave. For many guests, a day on the crater floor is the highlight of their safari.
How the crater formed
Around two to three million years ago, a large volcano collapsed in on itself after erupting, leaving the caldera you see today. It is often described as the world’s largest intact, unflooded caldera. The rim sits at about 2,300 metres, which explains the cool, misty mornings.
The Ngorongoro Conservation Area
The crater is part of the wider Ngorongoro Conservation Area, a UNESCO World Heritage Site. Unlike a national park, the area is shared by wildlife and Maasai pastoralists, who graze cattle on the highlands. It also includes Olduvai Gorge, one of the most important sites for the study of human origins, and the Ndutu plains, where the migration calves each year.
Wildlife on the crater floor
- Black rhinos: the crater is one of the best places in Tanzania to see them.
- Lions and spotted hyenas: both common and often seen hunting.
- Large herds: wildebeest, zebras, buffalo, gazelles and elands.
- Elephants: mostly older bulls, often in the Lerai Forest.
- Hippos: in the Ngoitoktok spring and swamps.
- Flamingos: on Lake Magadi when water levels suit them.
There are no giraffes or impalas on the crater floor. The walls are too steep, and the crater lacks the tall trees giraffes feed on.

Best time to visit
The crater is good all year because water and wildlife are permanent. The dry season from June to October has the clearest views and the coldest mornings. The green season from November to May brings lush scenery and fewer vehicles. Leave early to avoid the midday rush.
Where to stay
- On the crater rim: the best position for an early descent and the famous views. It is cold at night, so rooms usually have fireplaces or heaters.
- In the Karatu highlands: coffee farms and lodges about 30–45 minutes from the gate, warmer and better value.
Combining the crater with other parks
The crater sits between Arusha and the Serengeti, so most safaris stop here on the way in or out. It pairs well with Lake Manyara and Tarangire. Short on time? Crater & Manyara Quick covers the crater in three nights. For a longer trip, The Northern Loop adds Tarangire and the Serengeti.
Tips for a better crater day
- Bring a warm layer. The descent at dawn is cold.
- Take binoculars for rhinos, which are often far off.
- Ask your guide to start at the quieter side of the crater.
- Bring a camera cloth. The floor is dusty in the dry season.
