Ol Doinyo Lengai
ol Doinyo Lengai
Overview
Ol Doinyo Lengai, often referred to as the “Mountain of God” in the Maasai language, is an active volcano located in the Great Rift Valley of northern Tanzania. Towering at 2,962 meters (9,718 feet), this iconic volcano is one of the most unique geological features in the region and is known for its extraordinary volcanic activity and cultural significance. Ol Doinyo Lengai is the only active volcano in the world that erupts natrocarbonatite lava, a rare type of lava that is much cooler and more fluid than typical volcanic lava.
This impressive volcano lies near the southern shore of Lake Natron, a highly alkaline body of water that is another important attraction in the area. For adventurers, a hike to the summit of Ol Doinyo Lengai offers both a challenging trek and the chance to witness active volcanic vents. The combination of dramatic landscapes, Maasai culture, and unique geology makes Ol Doinyo Lengai a must-visit for those exploring the Rift Valley region.
Key Attractions
Natrocarbonatite Lava
Ol Doinyo Lengai’s claim to fame is its highly unusual natrocarbonatite lava, which is significantly cooler than typical basaltic or andesitic lava, flowing at temperatures as low as 500–600°C (932–1,112°F). This lava is extremely fluid and black in color when it first emerges, but it rapidly turns white as it cools and reacts with moisture in the air, forming a chalky substance. Due to the lower temperature, the lava poses a relatively low risk for hikers and is a unique phenomenon that can only be observed at this volcano.
Lake Natron
Located just north of the volcano, Lake Natron is one of the most alkaline lakes in the world, with high concentrations of sodium carbonate that create stunning red and pink hues, especially during the dry season. The lake is a critical breeding site for millions of lesser flamingos, making it a significant birdwatching location. The area surrounding Lake Natron is arid and otherworldly, with salt flats and shallow waters that reflect the skies, offering a beautiful, surreal landscape to explore after hiking Ol Doinyo Lengai.
Climbing Ol Doinyo Lengai
Climbing Ol Doinyo Lengai is a challenging but rewarding adventure. The trek to the summit typically begins late at night or in the early morning hours to take advantage of cooler temperatures and to reach the summit by sunrise. The climb is steep and strenuous, with loose volcanic ash and sharp rocks along the way. However, the effort is worth it, as reaching the summit allows hikers to observe the volcanic activity and enjoy unparalleled views of the surrounding landscapes.
- Duration: The ascent usually takes 5-7 hours, with the descent taking 3-5 hours.

The summit crater often has small, active vents emitting steam and natrocarbonatite lava, providing a rare opportunity to witness volcanic activity up close. On a clear day, the views from the top stretch across the valley to Mount Meru and even Mount Kilimanjaro in the far distance.
Maasai Culture
Ol Doinyo Lengai holds deep cultural significance for the local Maasai people, who consider it a sacred mountain. The Maasai believe that the mountain is the dwelling place of their deity Engai (or Enkai), who controls the rain and fertility of the land.
