Known by the Maasai people as the "Mountain of God", Ol Doinyo Lengai is nothing short of spectacular. Rising majestically from the Great Rift Valley floor to a height of 2890m, Ol Doinyo Lengai is the only active volcano on planet that erupts carbonatite lava. This type of lava is very unique because temperatures of these lavas are only around 500°C, about half the temperature of normal basalt lavas, and its lava flows with a viscosity almost as fluid as water.
Described by others as a scientifically precious, geochemical shrine, Oldoinyo lengai's is quite a physically demanding climb. Its steep slope makes it a challenge to climb up as well as to climb back down and the day time heat is unbearable. The best time to climb the mountain is at night when the temperatures are lower. This allows the climber to witness the amazing sunrise at the summit and come back down before the scorching heat kicks in.
Given the long transfer distance, it is best to trek Ol Doinyo Lengai as part of a 3 day tour. Below is a standard 3 day itinerary for Ol Doinyo Lengai but keep in mind this climb can be an addition to a longer safari tour depending on your preference.
