Lake Natron sits in the Great Rift Valley close to the Kenyan border, in some of the hottest and most dramatic landscape in Tanzania. It is a shallow soda lake with red and pink salt flats, and it lies at the foot of Ol Doinyo Lengai, an active volcano sacred to the Maasai. It is not a national park, and it feels remote.

Why flamingos come here

Lake Natron is the most important breeding site for lesser flamingos in East Africa. Its caustic, alkaline water keeps predators away from nests on the mud flats, and the algae that grow in the lake are a key food source. Large numbers gather in the breeding season, often after the rains. Numbers vary a lot from year to year.

Visitors watch from the shore at a distance. The breeding colonies are far out on the flats and must not be disturbed.

Ol Doinyo Lengai

“The Mountain of God” in Maa rises to about 2,960 metres above the lake. It is the only active volcano in the world known to erupt natrocarbonatite lava, which cools to white rather than black. The climb starts around midnight to avoid the heat and reaches the crater rim at sunrise. It is steep, loose and demanding, and suitable only for fit hikers with a local guide.

Things to do at Lake Natron

ActivityTime neededDifficulty
Walk to the flamingo shore1–2 hoursEasy
Engare Sero waterfall walk2–3 hoursModerate, wading in a river
Engare Sero footprints1 hourEasy
Maasai village visit1–2 hoursEasy
Ol Doinyo Lengai climb6–8 hours overnightVery hard

The Engare Sero footprints are a set of ancient human footprints preserved in volcanic mud near the lake. The waterfall walk follows a gorge upstream to a pool where you can swim.

Best time to visit

June to October is dry and more comfortable, and the lake’s colours are strongest as it shrinks. Flamingo numbers depend on rain and breeding conditions, so ask us for recent reports when you plan. The rainy months make roads harder.

Getting there

The road from Arusha is long and rough, passing through Maasai country and small settlements. There is also a route between Lake Natron and the northern Serengeti, which makes it a good link on a longer trip. Private light-aircraft charters are possible but costly.

Where to stay

A small number of tented camps and lodges sit near the lake and the Engare Sero river. They are simple compared with Serengeti camps, but comfortable, and well placed for early walks before the heat.

How to include it

Lake Natron is best as a two-night stop on a trip of eight nights or more. It adds scenery, walking and culture after days of game drives. Our Grand Northern safari can be adapted to include it. For a shorter trip, the Ngorongoro Crater and Lake Manyara offer Rift Valley views with less driving.

Frequently asked questions

Salt-loving microorganisms in the shallow, alkaline water produce red and orange pigments, especially in the dry season when the lake shrinks.

No. The water is highly alkaline and can burn skin and eyes. Swimming is possible in the freshwater Engare Sero river nearby.

By road from Arusha, a long drive on rough roads, or from the northern Serengeti. It is usually visited as a two-night detour.
