Trekking Oldonyo Lengai Volcano

Mountain Lenkai (normally known as "Ol'doinyo Lengai") rises about 2,100 meters above the east african rift valley floor to a height approximately 2,880 m. The name Ol'doinyo Lengai which means "Mountain of God" originates from the Maa language (the Maasai's language) from Ngorongoro area. The Maasai people say prayers to God "Enkai" or "Engai" whom the Maasai believe is the Creator of all things on this active volcanic mountain.
Ol'doinyo Lenkai is the only active volcanic mountain in the east african rift valley region which attracts many geologists from all over the world who come for research. Despite the fact that Ol'doinyo Lengai's volcano erupts frequently there are no records of injuries or deaths. Geologists tell that Ol'doinyo Lenga's lava is not as hot as other volcanoes lava recorded in the world. Of particular interest is the carbonated lava which is dark brown upon extrusion, but reacts very rapidly changing firstly as it hydrates and then a second alteration and the minerals change the rock to a white colour. The Maasai believe that the white rock symbolizes the white beards of "Enkai".
We are one of the few companies that offer regular hikes up this mountain. This 9,442 feet high mountain requires real determination to climb because of the steep slopes. However, climbing Ol'doinyo Lengai doesn't require any technical climbing skills to get to the peak and is well worth doing. At the summit, the small cones formed by lava can be seen on the crater rim. It takes three days to hike Ol'doinyo Lengai.
After climbing Lengai, we recommend you book our trip around Lake Natron. Lake Natron is the largest lake in East Africa which accommodates numerous flamingos and other birdlife.
