Ol Doinyo Lengai, meaning "Mountain of God" in the Maasai language, is an active volcano located in the Gregory Rift, south of Lake Natron in Tanzania. At 2,962 meters (9,718 feet), it's the only active volcano in Tanzania and one of the few carbonatite volcanoes in the world. Its unique natrocarbonatite lava erupts at relatively low temperatures (500-600°C) and appears black in daylight but glows orange at night.
Climbing this sacred mountain offers a unique adventure combining geology, culture, and spectacular Rift Valley views.
Dry Seasons (Recommended):
June to October & December to February offer the best climbing conditions with clear skies and minimal rainfall.
Shoulder Seasons:
November & March - good conditions but chance of occasional showers.
Rainy Seasons (Challenging):
April to May - heavy rainfall makes the steep ash slopes slippery and dangerous. Climbing during this period is not recommended.

Ol Doinyo Lengai is technically more challenging than standard Kilimanjaro routes due to its steep slopes (35-40° incline) and loose volcanic ash/scree. However, it's much shorter (4-6 hour ascent) and at lower altitude (2,962m vs 5,895m). The main challenges are the steep grade and slippery ash descent. It requires good fitness and trekking experience but no technical climbing skills. The night ascent adds an adventurous element. Success rates are 85-90% for fit climbers.
Ol Doinyo Lengai has frequent but small-scale eruptions. Our experienced guides monitor volcanic activity closely and will not proceed if conditions are unsafe. The volcano typically exhibits gentle effusive eruptions rather than explosive ones. We maintain safe distances from active vents and fumaroles. Safety equipment including gas masks (for SO2) is carried. We have emergency evacuation plans and satellite communication. Climbing with experienced guides who know the volcano's behavior patterns significantly reduces risks.
Our all-inclusive packages include: All park and volcano permits, certified volcano guide and assistant guides, 4x4 transfers from Arusha/Moshi, accommodation (camping or basic lodge), all meals during the trip, drinking water, Lake Natron entry fees, emergency first aid kit, and communication equipment. Not included: International flights, travel insurance, Tanzania visa, personal trekking gear (headlamps, poles, etc.), tips for guides and crew, accommodation before/after climb, alcoholic beverages, personal expenses.
Night climbing is recommended for several reasons: 1) Avoid the extreme heat of daytime (temperatures can exceed 35°C/95°F), 2) Reach the summit for sunrise - the most spectacular time with views over Lake Natron, 3) Potentially see glowing lava in the dark, 4) The ash is cooler and more stable at night. Day climbs are possible but extremely hot and less scenic. We carefully time the ascent to reach the summit just before sunrise for optimal experience and photography opportunities.
Essential equipment includes: Sturdy hiking boots with ankle support, trekking poles (highly recommended for descent), headlamp with extra batteries (night climb), gaiters (to keep ash out of boots), dust mask or buff, warm layers (summit can be cold at sunrise), gloves, sun protection (hat, sunglasses, sunscreen), camera with protective bag against dust. We provide technical safety equipment like gas masks when needed. A detailed packing list is sent upon booking.
Absolutely! Ol Doinyo Lengai combines perfectly with: 1) Northern Circuit Safari (Serengeti, Ngorongoro, Tarangire) - add 2-3 days after your safari, 2) Kilimanjaro climb - do Lengai first as acclimatization (recommended) or after as a shorter adventure, 3) Zanzibar beach holiday - relax after your volcano adventure, 4) Cultural tours in northern Tanzania. We create customized multi-activity itineraries combining volcano climbing, safari, and beach. Contact us for custom combinations.
