The Ol Doinyo Lengai is located on the western edge of the rift, 160 kilometers west of Kilimanjaro, northeast of Ngorongoro Crater and south of Lake Natron. It culminates at 2960 meters altitude.
Currently in a calmer phase (?), the last eruption was in 1966 and from 1994 to 1998 it has shown by its tremors that it is far from being asleep.
In 1998, the eruption even completely filled the crater and the lava started to overflow.
The ascent of this volcano is for people experienced in sporting treks, because the slope is often steep, with some tricky passages to cross.
This trek is physically demanding and not recommended for beginners.
This volcano is located in Maasai territory and only local guides are allowed to accompany walkers. They prohibit agencies’ guides to access this mountain.
The departure to the trek is done around midnight in order to get to the top before hot weather is aggravated by soil temperature. The return is at noon.
This trek requires at least three days of availability:
- ½ day trip (Arusha-Lake Natron). In the afternoon, visits and various walks around the lake. Overnight camping Ngare Sero.
- Ascension back to camp, rest and / or swimming in the warm waterfalls.
