If there is one place in Tanzania in East Africa that feels like it belongs to another planet, it’s Lake Natron in Tanzania. Famous for its deep reds, highly alkaline waters, harsh temperatures, breathtaking volcanic backdrop, and millions of flamingos, this lake is both beautiful and deadly. It sits within the dramatic East African Rift, where shifting tectonic forces and volcanic activity shape the landscape daily.
Unlike the wildlife-rich Serengeti of Tanzania or the lush safari scenes of Serengeti National Park Safari, Lake Natron in Tanzania is raw, extreme, and astonishingly unique. Here, you’ll find salt-loving microorganisms painting the water crimson, steaming hot springs along the shore, fossil footprints of ancient humans, and a breeding ground for millions of lesser flamingos.
Whether you’re exploring it as part of African safari Tanzania adventures or combining it with stops at Serengeti Mara during the Great Migration, Lake Natron offers a travel experience unlike anywhere else.
What Is Lake Natron in Tanzania?
Lake Natron in Tanzania is a shallow, highly alkaline salt lake located in northern Tanzania near the Kenyan border, known for its deep red waters caused by salt-loving microorganisms, extreme temperatures, and its role as the primary breeding ground for millions of lesser flamingos.
It is:
- A soda lake rich in sodium carbonate
- Fed by mineral-rich hot springs
- Situated at the base of Ol Doinyo Lengai, an active volcano
- Located inside the Gregory Rift of the East African Rift system
Due to the harsh water, animals that died in the water often become calcified—giving rise to the myth that the lake “turns animals to stone.”
Where Is Lake Natron Located?
Lake Natron lies in northern Tanzania, stretching into southern Kenya. It is part of the remote, arid landscapes north of the Ngorongoro Conservation Area and east of Tanzania’s Serengeti.
Key location details:
- Region: Northern Tanzania
- Rift Valley: Gregory Rift (eastern branch of the East African Rift)
- Nearby attractions:
-
Oldoinyo Lengai (active volcano)
-
Engare Sero waterfalls
-
Massai communities
-
Easy access from Safari Lodges in Tanzania
-
Its remote location is part of its mystique—vast, untouched, and elemental.
Why Does Lake Natron Turn Red?
The deep reds and oranges are caused by:
- Salt-loving microorganisms (halophiles): These thrive in extreme alkalinity and heat.
- Cyanobacteria with red pigments: Their photosynthetic pigments produce the lake’s signature colors.
- High evaporation during the dry season: More evaporation → higher salinity → deeper red tones.
The waters of Lake Natron can reach pH levels above 10.5, making it one of the most alkaline lakes in the world.
Flamingos at Lake Natron—One of Earth’s Greatest Bird Phenomena
Lake Natron in Tanzania is
The primary breeding ground for 75% of the world’s lesser flamingos.
Well over two million flamingos flock here during breeding season.
Why? The lake’s caustic, salty environment effectively deters predators. The lake becomes a natural fortress.
Flamingos feed on cyanobacteria in the lake, turning their feathers bright pink. The lake’s temporary islands created by evaporation serve as safe sites for nesting.
This sight rivals even the wildlife spectacles of Serengeti Mara and the Great Migration.
Oldoinyo Lengai—The Volcano Behind Lake Natron’s Chemistry
To understand Lake Natron, you must understand Ol Doinyo Lengai, the “Mountain of God” for the Maasai.
This is:
- The world’s only active carbonatite volcano
- A source of minerals like sodium carbonate
- The primary reason for the lake’s high alkalinity
Volcanic ash, lava, and mineral deposits feed into the lake through hot springs, creating the extreme chemistry that shapes its entire ecosystem.
Climbing Ol Doinyo Lengai is a popular activity for adventure seekers visiting Lake Natron in Tanzania.
Climate, Temperature & Seasons at Lake Natron
The climate is hot, dry, and harsh—like desert conditions.
Dry Season (June–September)

The Unique Ecosystem of Lake Natron
Despite being deadly to most wildlife, a harsh but fascinating ecosystem survives here.
- Salt-loving microorganisms: Responsible for deep reds.
- Freshwater wetlands: Found around the lake edges.
- Alcolapia fish species: Small tilapia adapted to extreme conditions.
- Migratory birds: There are tens of thousands of migratory birds in addition to flamingos.
This stark environment is unlike anything in Serengeti National Park Safari, but equally astounding.
