Ol Doinyo Lengai Tours

This stunning volcano is located in a remote region of Tanzania near the Gregory Rift, just south of Lake Natron. It’s known by the Maasai people as “Mountain of God” and its impressive lava fountains harden midair—a real geological oddity. 

Ol Doinyo Lengai’s erupting hornitos—the fragile rock formations that surround active volcano vents—draw thrill-seeking climbers to its slopes each year. It’s also the only known volcano to spout carbonatitite—a low-temperature lava that is black like oil, moves quickly like water, and cools to a whitish powder.

Travelers have put this incredible volcano at the top of their bucket lists for a number of reasons—not the least of which is its truly unique way it erupts. Ol Doinyo Lengai is a scenic place for hiking and climbing and because of its rare lava, the textured hillsides look otherworldly. 

Practical Info

Ol Doinyo Lengai’s last major eruption was in 2006. It is 110 kilometers from Arusha and stretches 2,878 meters above Lake Nartron.
