A blood-red soda lake beneath the Maasai’s sacred “Mountain of God” — one of East Africa’s most dramatic and least-visited landscapes.
On This Page
Lake Natron is a shallow soda lake in northern Tanzania’s Rift Valley, famous for its striking red and orange colours caused by salt-loving microorganisms, and for sitting at the foot of Oldoinyo Lengai — the Maasai’s sacred “Mountain of God” and the only volcano on Earth that erupts natrocarbonatite lava. Together, the lake and volcano form one of Tanzania’s most dramatic and least-visited landscapes.

Lake Natron’s high alkalinity and mineral content give it a red hue in the dry season, and the lake is the only regular breeding site in East Africa for lesser flamingos, who nest safely on its salt crust islands, out of reach of most predators. The surrounding landscape is stark and volcanic, dominated by views of Oldoinyo Lengai rising sharply from the Rift Valley floor.
Lake Natron’s water can reach temperatures of up to 60°C and a pH as high as 10.5 — alkaline enough that dead animals in the lake sometimes become calcified, preserved in the mineral-rich water.
| Season | Conditions | Best For |
|---|---|---|
| Jun – Oct | Dry season, stable scree footing for climbers | Safest, most reliable Oldoinyo Lengai climbs |
| Jan – Feb | Short dry spell | Good secondary window |
| Mar – May | Long rains, slippery ash slopes | Generally avoided for the volcano climb |
| Nov – Dec | Short rains | Check conditions before booking |
Most visits start from Engare Sero village on the shores of Lake Natron, roughly a 4–5 hour drive from Arusha. The Oldoinyo Lengai climb typically begins at night from a base camp near the mountain’s foot, so the village is usually reached the afternoon before.
