Overview
Lake Natron is one of the most visually striking and ecologically important destinations in northern Tanzania. This shallow alkaline lake sits at the base of Ol Doinyo Lengai, the only active carbonatite volcano in the world, and is the primary breeding ground for approximately 2.5 million lesser flamingos in East Africa, representing about 75 percent of the global population. The lake's extreme alkalinity, with a pH that can exceed 12, and temperatures reaching up to 60 degrees Celsius in certain areas, create conditions that are inhospitable to most life forms but ideal for the blue-green algae that flamingos feed upon. The result is a landscape that appears almost otherworldly, with the lake's surface shifting between deep reds, oranges, and pinks depending on the concentration of algae and mineral deposits. Visiting Lake Natron is an adventure in itself. The journey from Arusha passes through Maasai land, dramatic Rift Valley scenery, and increasingly remote terrain. Activities at the lake include guided walks to flamingo breeding colonies, hikes to nearby waterfalls, a challenging climb of Ol Doinyo Lengai (best attempted overnight for a sunrise summit), and cultural visits to local Maasai communities. The nearby Engaresero footprints, ancient hominid tracks preserved in volcanic ash, add an archaeological dimension to the visit. Lake Natron is best suited for adventurous travelers seeking off-the-beaten-path experiences. Accommodation is limited to a few tented camps, and the area receives very few visitors, ensuring an authentic and uncrowded experience. The lake is often incorporated into custom northern Tanzania itineraries as a side trip from the main safari circuit.
