Hike Oldoinyo Lengai: Tanzania’s Sacred & Active Volcano

Oldoinyo Lengai, the “Mountain of God,” is a one-of-a-kind natural wonder in northern Tanzania. It is the world’s only active carbonatite volcano, making it a rare destination for adventure seekers, geologists, and travelers looking beyond a traditional safari.

Why Oldoinyo Lengai is Unique

This sacred volcano is a geological marvel. Unlike any other active volcano on Earth, it erupts natrocarbonatite lava, which is cooler, black in daylight, and turns white as it hardens. Located in the Great Rift Valley just south of Lake Natron, it reaches 2,962 meters and offers unparalleled 360-degree views from its summit.

The Oldoinyo Lengai Summit Hike

The climb is a challenging but rewarding overnight adventure.

• The Challenge: A steep, 6-7 hour ascent on loose scree, typically starting at midnight to reach the crater at sunrise.

• The Reward: Witnessing an active volcanic crater and panoramic views of Lake Natron, the Ngorongoro Highlands, and Mount Kilimanjaro.

• Preparation: Hikers need good fitness, a warm jacket for the summit, and water. The route allows a morning descent in cool shade.

What You Can See and Do 

• Summit the Volcano: Experience the thrill of standing on the rim of an active crater.

• View Lake Natron: From the top, see the vast soda flats of Lake Natron, a key breeding ground for flamingos.

• Walking Safari: The lower slopes are home to wildlife like zebras and gazelles, often seen with a Maasai guide.

• Cultural Visit: Explore nearby Maasai bomas to learn about the culture of the people who hold this mountain sacred.

How to Visit Oldoinyo Lengai

The most practical base is Lake Natron Camp. Visiting requires careful planning:

• Guides & Permits: A local Maasai guide and hiking permit are essential.

• Best Time to Hike: During the cooler, dry seasons (June-October and December-February).

• Safety Note: Volcanic activity is monitored; summit access depends on current conditions.

Important: This is a strenuous hike. It is recommended for physically fit travelers prepared for a rugged, high-altitude adventure.
