Mount Oldoinyo Lengai — the Maasai 'Mountain of God' — is one of the most extraordinary and unusual trekking destinations in the world. As the only active carbonatite volcano on Earth, it produces lava that is unlike anything found elsewhere — uniquely fluid at relatively low temperatures, cooling to a striking white and black surface that makes the crater look almost lunar. Rising to 2,962 metres at the edge of the Great Rift Valley above Lake Natron, this is an adventure for experienced trekkers who want something genuinely rare.
The climb typically begins at midnight, ascending steeply through darkness to reach the summit crater at sunrise — a moment of absolute, breathtaking reward. From the rim, views stretch across Lake Natron's flamingo-pink shores, the Rift Valley floor, and on clear days, as far as Kilimanjaro. The cultural dimension is equally powerful: the Maasai people consider Lengai sacred, and trekking here with a local guide brings rare insight into spiritual traditions that have shaped this landscape for centuries.
Shammah Wonders Safaris combines Lengai with a Lake Natron day, allowing you to visit the flamingo-rich lake shores before or after the climb. This experience is available as a standalone 2–4 day adventure or combined with a Serengeti safari or Zanzibar holiday.
