Mount Oldonyo Lengai routes

Oldoinyo lengai� means “the mountain of god� in the maasai language. The summit of this strato-volcano is 2962 metres above sea level, and affords direct views into the caldera of tanzania’s only officially-certified active volcano, and the world’s only carbonatite volcano; records of eruptions have been maintained since 1883, the largest of which deposited ash 100 kilometres away in loliondo on the kenyan border to the north west.

It is located in northern tanzania lying just south of lake natron in the rift valley, in the heart of maasai country, and locally regarded as a sacred mountain. Looking north from its summit crater, the hot barren salt flats of lake natron stretch into the distance. To the south stretch the crater highlands and the ngorongoro game reserve. The eastern horizons dominated by kilimanjaro and to the west the forested escarpments and hills comprising the western slopes of the rift valley. Every seven years lengai erupts and plumes of smoke billow out of the crater.
