Ol Doinyo Lengai, meaning “Mountain of God” in the Maasai language, is an active volcano that towers above the Rift Valley near Lake Natron. Rising to 2,962 meters (9,718 ft), it is the only volcano in the world that erupts carbonatite lava, a rare, low-temperature lava that creates dramatic landscapes and unusual formations.
This challenging overnight trek begins from Ngaresero village near Lake Natron. The climb starts just after midnight to avoid the intense daytime heat, with hikers reaching the summit at sunrise for breathtaking views of the Rift Valley, Lake Natron, and distant peaks like Mount Meru and Kilimanjaro on clear days.
The itinerary also includes time to relax at Lake Natron, known for its flamingos, waterfalls, and stark volcanic scenery, making it a perfect combination of cultural, geological, and adventure travel.
