Lake Natron
Lake
A caustic soda lake beneath an active volcano, and the only regular breeding site in East Africa for lesser flamingo.
Natron is not a normal safari stop. It is hot, harsh and strange — a shallow, highly alkaline lake that turns deep red in places from the algae that thrive in it, under the perfect cone of Ol Doinyo Lengai, the only volcano on earth that erupts natrocarbonatite lava.
Almost the entire East African population of lesser flamingo breeds here, precisely because the caustic water keeps predators away. The landscape is the draw as much as the wildlife: escarpments, waterfalls in the gorges, and Maasai communities living in country that looks unlivable.
Add it if you want your trip to include something other than game drives, or if you intend to climb Lengai overnight — a brutal but memorable ascent that starts at midnight.
From our guides
Stop here on the drive between the Serengeti and Arusha rather than making a special trip. The road down from the north is spectacular.
Why come here
- The main breeding ground for East Africa’s lesser flamingo
- Ol Doinyo Lengai — a genuinely unusual active volcano
- Waterfalls and gorges in the Rift escarpment
- Strong Maasai cultural presence
The wildlife
Flamingo in vast numbers when conditions suit. Otherwise limited large game — this is a landscape and cultural destination rather than a game-viewing one.
When to visit
June to October for the easiest road access. It is extremely hot year-round, and the approach can be difficult after heavy rain.

Things to do
Experiences here
Lake Natron, answered
Walk to the waterfalls in the Ngare Sero gorge, see the flamingo, and look at a landscape that resembles nowhere else in Tanzania. Some people climb Ol Doinyo Lengai overnight, which is brutal and memorable in roughly equal measure.
No. It is highly alkaline and caustic. The gorge waterfalls nearby are fresh water and are where you swim.
Very. It starts around midnight, is steep and loose the whole way, and takes five to six hours up. Only attempt it if you are genuinely fit and have acclimatised. It is not a walk.
