Lake Natron is one of the Rift Valley’s starkest and most forbidding lakes.
However, the hostile conditions are ideal for flamingos and the lake is their most important breeding site in Africa. Its waters are shadowed by the 2878m-tall Ol Doinyo lengai (the ‘Mountain of God’ in Maasai), which is one of East Africa’s most active volcanoes. Its other worldly caldera can be ascended in 5-6 hours, ideally at night.
