Lake Natron in Tanzania 2025

Lake Natron is located in the Arusha Region, on the north of the country. It is fed by mineral-rich hot springs and Southern Ewaso Ng'iro River that rises in central Kenya. This huge shallow lake, 57 km long and 22 km wide, is home to lots of natural wonders. The temperature of the water is around 40 °C, and it contains lots of salt and soda. It actually got its name from the mixture of soda and minerals, called natron. Usually the pH level is above 10 and sometimes it can even be 12.

These shallow and very salty waters are dangerous for most of the wildlife. They can burn skin and eyes. These characteristics make Lake Natron one of the deadliest spots in the country. But its alkaline waters support an ecosystem of salt marshes, freshwater wetlands, and flamingos.

Amazing red, pink, and orange colours make the lake a unique and very popular destination for visitors. The variety of colours changes due to the evaporation process and concentration level of cyanobacteria. The best months to visit Lake Natron are the coolest ones—from June to August. Dry season is perfect for walking and trekking around the lake. During the dry season, the water in the lake evaporates and concentration of salts and microorganisms gets higher, creating amazing colours. The wet season brings lots of rain and thunderstorms, which damage most of the trails and even roads around this area.
