Climbing Mount Oldonyo Lengai is an incredible experience because you will encounter an active volcano and truly unique volcanic features and activities. It is a genuine challenge that brings both remarkable highs and testing lows.
Ol Doinyo Lengai You’re describing **Oldoinyo Lengai**, an active volcano in northern Tanzania, East Africa. It’s famous for its volcanic cone with two craters, the northern one having erupted in recorded history. What makes Oldoinyo Lengai truly unique is its eruption of **natrocarbonatite lava**, a rare type of magma that is much cooler and more fluid than typical lava. Its eruptions, especially those in 2007–2008, had a significant impact on the nearby environment and communities.
Ol Doinyo Lengai is located in the Arusha region of Tanzania, approximately 16 kilometers (9.9 miles) south of Lake Natron and 120 kilometers (75 miles) northwest of Arusha city. The volcano’s summit was first explored during the early 20th century, between 1904 and 1915. As of 2012, the surrounding region is home to about 300,000 people. Livestock farming remains the main economic activity, but tourism is steadily growing in importance due to the volcano’s unique geological features and cultural significance.
The vegetation around Ol Doinyo Lengai is predominantly grassland, extending up to an elevation of about 1,750 meters (5,740 feet) above sea level. Volcanic ash from the eruptions enriches the soil, supporting the growth of nutrient-rich plants in the area. The region experiences two distinct wet seasons: from March to May and again from October to December, which help sustain the lush grasslands and surrounding ecosystems.
The ideal time to climb Mount Oldonyo Lengai, an active stratovolcano in Tanzania, is during the dry seasons—from June to October and January to February. During these months, the weather tends to be more stable with minimal rainfall, ensuring safer and more enjoyable trekking conditions. Trails are drier and less slippery, making the ascent easier, and clear skies often provide breathtaking views of the surrounding landscapes. Planning your climb in these periods maximizes both safety and the overall experience.
It’s important to avoid the rainy season (March to May), as the trails can be slippery and difficult to navigate. The weather during this time can also be unpredictable, making climbing more hazardous.
