Ol Doinyo Lengai – The Sacred Mountain of Fire

Climb the Only Active Carbonatite Volcano in the World with Mashirima Tours

Towering dramatically over the Great Rift Valley floor in northern Tanzania, Ol Doinyo Lengai—meaning “Mountain of God” in the Maasai language—is one of Africa’s most fascinating geological wonders. Located near Lake Natron and not far from Ngorongoro Conservation Area, this active volcano is both a natural marvel and a sacred site to the Maasai people.

Ol Doinyo Lengai is the only active volcano in the world that erupts natrocarbonatite lava, which is unique for being much cooler and darker than typical lava. This rare phenomenon, paired with its spiritual significance and challenging climb, makes it a must-visit for adventurous travelers and volcano enthusiasts.
