Oldoinyo Lengai Climbing Expedition

Oldoinyo Lengai Climbing Expedition

Mount Oldoinyo Lengai climbing expedition is one of the major attractions in Tanzania. Oldoinyo Lengai is also known as “Mountain of God”. The Mountain is an active volcano located in the Gregory Rift, south of Lake Natron within the Arusha Region of Tanzania.

Scaling the mountain’s heights is a feat that takes plenty of perseverance and it’s important to undergo acclimatization before climbing the mountain to reduce the risk of altitude sickness. The expeditions can be under taken privately accompanied by the mountain guide and porters or in group subject to availability.

We buy fresh produce and other food locally, and to ensure high standards of hygiene the food is prepared by our own staff. We can cater for special dietary requirements with advance notice at no extra charge.

You only require bottled water on the first and last day. The other days we will boil water or add purifying tablets then filter using MSR water filtering pump before refilling in your water bottles in the morning.

Oldoinyo Lengai Climbing Expedition Itinerary

Arusha – Lake Natron (Ngare Sero)

Departing Arusha in the morning you drive to Mtu-wa Mbu (Lake Manyara) for lunch. After lunch you drive north along the bottom of the Great Rift Valley wall to Lake Natron and the village of Ngare Sero at the base of Ol Doinyo Lengai. Overnight at a campsite by the lake.

Lake Natron – Ngare Sero – Ol Doinyo Lengai

From Lake Natron to Ngare Sero is a 3-hour walk. Lengai is best approached from the west. Between Ngare Sero and Lengai’s lower slopes is another 3 hours walk. The vehicle will go o­n ahead here so that it is there to take you up this large gully and so saving you at least 6 hours of walking. Overnight camp in the gully.

Ol Doinyo Lengai summit – Lake Natron campsite

A very early start in order to gain as much height as possible in the cool of the morning. Sun hats and a large water in-take are essential. Descend by the same route. Great care should be taken o­n the way down: loose volcanic gravel o­n bare rock makes it perilous going in places. Overnight at the Lake Natron camp site.

Lake Natron – Arusha Town

Departing after breakfast you drive back to Arusha town. Drop-off.

National Park Fact File

Oldoinyo Lengai is in the Lake Natron area in the north of Tanzania, right on the Kenyan border and extremely off the beaten track. The drive to Lake Natron, with the imposing volcano Oldoinyo Lengai in the background is surreal and breathtaking. The landscape has been pock-marked with volcanic activity; mini calderas and the great Rift Valley punctuate the horizon. After settling in to camp at the foot of the slopes of Oldoinyo Lengai and stretching your legs we recommend that you venture up to the nearby waterfalls for a refreshing swim.

The base of Ol Doinyo L’Engai, on the Engaruka Plains, lies at about 800m. The Masai’s Mountain of God is the only active carboniferous volcano in the world and as such provides a genuinely unique opportunity for adventure-lovers and photographers. The steep ascent to the top (currently just under 3000m) requires determination and good fitness levels, but the views alone are more than worth the effort. It is usually possible to stroll over solidified lava flows, and walk amongst the lava cones belching out sulfurous gases. Ideally the hike begins at 12.30am, and the summit is reached as the sun rises over the wind-scoured expanse of the valley below.

You will need a fleece and hat for the summit, as the wind can be chilly at 3000m. Take a torch, and enough batteries to last till sunrise. Enjoy the views and explore the solidified lava flows before descending back to the vehicle and continuing on to your next destination.

The “Mountain of God” for the Masai Tribes – altitude 2886 meters (9524 feet) Ol Doinyo Lengai is a volcano located in Tanzania and is part of the volcanic system of the Great Rift Valley in eastern Africa.
