Ol Doinyo Lengai means "Mountain of God" in Massai language. It is a steep around 2900 m high stratovolcano located in a section of the East-African rift valley in northern Tanzania, near the Ngorongongo and Serengeti National parks. The volcano is known for its unique type of natrocarbonatite lava and as such it is the only known active natrocarbonatite volcano on earth. In August 2003, Tom Pfeiffer together with Marco Fulle, Stephane Granier and Martin Rietze undertook an expedition to this volcano organized by Fred Belton, is a passionate and experienced climber of Lengai since many years and guides an excellent expedition. During our stay, the activity was generally at a low level, but remarkable by its explosive character, which is regarded unusual for Lengai. All activity was confined to two cinder cones (misleadingly called hornitos, named T56B and T58B), which showed variable activity of lava fountains and strombolian activity, interrupted by repeated and spectacular collapses of the cones themselves.
Mount OlDoinyoLengai the holymountain of the Masai, situated in Arusha territory in Tanzania. It is discovered 240 kilometers toward the northwest of Arusha town, alongside the western bluff of the Great Rift Valley, sitting above Lake Natron on the fringe with Kenya. OlDoinyoLengai is alluded to by the Maasai people as the “Mountain of God", is the main dynamic spring of gushing lava in Tanzania. Rising wonderfully from the Great Rift Valley floor to a stature of 2890m, OlDoinyoLengai is the main dynamic spring of gushing lava on the planet that radiates carbonatite magma. This sort of magma is incredibly phenomenal in light of the way that temperatures of these magmas are simply around 500°C, about a huge part of the temperature of run of the mill basalt magmas, and its magma streams with a consistency almost as fluid as water. The mountain can be trekked in 6 hours, bearing dazzling points of view of the Great Rift Valley and volcanic courses of action in the Ngorongoro good countries as you get to the summit. It is a gutsy climb starting at first light. Remember this is a working wellspring of fluid magma, the mountain remains close to climb when we have discharges. Portrayed by others as a tentatively profitable, geochemical haven, Oldoinyolengai's is a noteworthy physically demanding climb. Its lofty slant makes it a test to climb and notwithstanding moving down and the daytime warm is vile. The best time to rise the mountain is around night time when the temperatures are lower. This empowers the climber to watch the surprising first light at the summit and return before the consuming warmth kicks in.

Dinner and overnight at campsite or lodge. you will begin your ascent of Ol Doinyo Lengai early in the night. Ol Doinyo Lengai is the only volcano in the world to erupt natrocarbonatite lava and is the most active volcano in Tanzania. With a height of 2586m/9370ft it was named Ol Doinyo Lengai or Mountain of God by the Maasai, and is a sacred site of pilgrimage for the Maasai and the dwelling place of their god Enkai.
