Ol Doinyo Lengai is the only remaining active volcanic mountain in Tanzania (major explosive eruptions have been recorded since 2007) though there are numerous small eruptions happen now and then. It is the only volcano in the world that erupts natrocarbonatite lava, a highly fluid lava that contains almost no silicon.

Natrocarbonatite lava is also much cooler than other lavas
The mountain is ideal for adventurous travelers who like to explore those unique areas in the world, such as photographers, trekkers and volcano lovers. Nevertheless Ol Doinyo Lengai is considered to be extremely hazardous and that safety cannot be assured. Trekking takes 1 day; though descending is tough’ It is always done with combination with safari to Serengeti and Ngorongoro.

It provides spectacular view of escarpment separating the Serengeti Plains from Lake Natron and the Rift Valley below.

Ol doinyo Lengai worshiped by “Maasai as Mountain of God” is located in the African Rift valley about 120 km North West of Arusha. It is nice safari when you combine with Ngorongoro Highland Hiking, which gives the opportunity to explore culture and view different volcanic features along the way before climbing the mountain. The climbing takes about 3 to 4 hours to reach the top, and the hike normally starts early hours in the morning to avoid the day intense heat in the Rift Valley; the best time to climb is from June to early March.
