4 Day Walking Safari With Oldonyo Lengai Treks requires 4-5 hours which is moderate exertion, the ascent is quite difficult and challenging because the mountain is very steep and climbers are exposed to the hot sun as there is almost not any shade.
The best time to climb the mountain is early in the morning before the sun gets too hot, Herds of zebra and wildebeest can sometimes be seen on the trip. A trip to the mountain can also cover other nearby areas of interest like Lake Natron, which is a breeding ground for all East African flamingoes and other birds. There are several Maasai bomas (villages) which can be visited on additional cost just talk to your driver guide if you are interested and one can also visit the nearby Mount Gelai which has geysers and a brilliant waterfall.
Departing Arusha in the morning drive to Mto-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 Oldonyo Lengai. Overnight at a campsite by the lake.
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 o¬n 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.
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 o¬n the way down: loose volcanic gravel o¬n bare rock makes it dangerous going in places. Overnight at the Lake Natron camp site.
Departing after breakfast you drive back to Arusha town. Drop-off at the hotel or to the airport for Zanzibar or connect flight back home.
