Overview
Ol Doinyo Lengai, known as the “Mountain of God” in the Maasai language, is an active stratovolcano located in the Ngorongoro Conservation Area of northern Tanzania. Standing at 2,962 meters (9,721 feet) above sea level, it is the only active volcano in the world that erupts natrocarbonatite lava, a rare type of lava that is significantly different from the basaltic lava found in most volcanoes. This unique volcanic feature and the dramatic landscapes surrounding it make Ol Doinyo Lengai a remarkable and awe-inspiring destination.

The mountain is a sacred site for the Maasai people, who regard it as the home of their God, Engai. With its frequent eruptions and the mesmerizing landscapes of the Great Rift Valley, Ol Doinyo Lengai attracts trekkers, adventurers, and photographers from all over the world.

Climbing Ol Doinyo Lengai
Climbing Ol Doinyo Lengai is not for the faint-hearted. The ascent is challenging, and climbers are required to have a reasonable level of physical fitness, stamina, and experience in mountain climbing. Unlike most volcanoes that emit molten lava, Ol Doinyo Lengai’s natrocarbonatite lava is cooler and flows more like a thick paste, giving the volcano its unique appearance. Climbers face steep, rocky terrain and loose scree on the way up, making the trek demanding.

• Route to the Summit: The most common route begins from the base of the mountain and takes climbers up the southern face, passing through volcanic ash, sand, and rocky sections. The climb can be completed in a single day, typically starting early in the morning to avoid the midday heat.
• Summit Views: The summit of Ol Doinyo Lengai offers breathtaking views of the surrounding landscape. From the top, climbers are treated to a panoramic vista of the Great Rift Valley, Lake Natron, and the expansive plains of the Maasai Steppe. On clear days, the view of the nearby Mount Kilimanjaro can also be seen in the distance.
• Difficulty Level: The climb is steep, and while it may not reach the technical difficulty of other high-altitude climbs, the conditions of the terrain make it a physically demanding experience. Climbers must also navigate the harsh environment, which includes high temperatures, the dry conditions, and the lack of shade.

Best Time to Visit
The best time to climb Ol Doinyo Lengai is during the dry season, which typically runs from June to October. During these months, the weather is more stable, and the trails are less slippery. The rainy season, from March to May, makes the trails more treacherous due to mud and loose volcanic ash, which can significantly slow progress.

For those visiting the surrounding areas, including Lake Natron and the Ngorongoro Conservation Area, the dry season also provides better conditions for exploring and wildlife viewing.

Wildlife and Ecosystems
While the primary draw of Ol Doinyo Lengai is its volcanic activity, the surrounding area is home to a variety of wildlife and ecosystems that make for a rich and diverse experience. The lower slopes of the mountain and the nearby plains are home to various species of animals and birds.

• Wildlife: The area around Ol Doinyo Lengai is teeming with wildlife, including herds of zebras, gazelles, and buffaloes. The open plains below the mountain are also frequented by lions, cheetahs, and leopards. Bird watchers will also find plenty of opportunities to see species like ostriches, vultures, and various waterfowl near Lake Natron.
• Lake Natron: Located to the north of the mountain, Lake Natron is a saline lake that is also a breeding ground for the famous flamingos that migrate to the area in large numbers. The stark contrast between the arid volcanic landscape and the vibrant pink flamingos is a photographer’s paradise.

Cultural Significance
Ol Doinyo Lengai holds immense cultural and spiritual significance for the Maasai people. They believe the mountain is a sacred place where their god, Engai, resides. The Maasai make pilgrimages to the mountain, offering prayers and sacrifices to honor their deity. The mountain’s eruptions are viewed by the Maasai as a sign of divine presence, and the volcano holds a deep connection to their traditions and spiritual beliefs.

Visitors to the area often have the opportunity to learn more about the Maasai culture, traditions, and way of life. The Maasai are known for their vibrant customs, distinctive clothing, and semi-nomadic lifestyle, which revolves around herding cattle.

Safety and Preparation
Climbing Ol Doinyo Lengai is a challenging endeavor, and proper preparation is key to ensuring safety throughout the trek.

• Acclimatization: The mountain’s high altitude and steep terrain require climbers to pace themselves to avoid altitude sickness. While Ol Doinyo Lengai is not as high as Mount Kilimanjaro, it’s still essential to take it slow and rest during the climb to ensure a successful summit.
• Guides and Porters: It is highly recommended to climb with a local guide who knows the route, the terrain, and the conditions of the volcano. Guides also help ensure the safety of climbers and can provide valuable information about the geology, history, and ecology of Ol Doinyo Lengai.
• Essential Gear: Climbers should wear sturdy hiking boots, a hat, and sunscreen, as the conditions can be hot and dry. A good set of trekking poles is helpful for stability on the rocky terrain. Adequate water and snacks are also important, as there are few opportunities to replenish supplies during the ascent.
