🌋 Why Climb Mount Ol Doinyo Lengai?
Climbing Ol Doinyo Lengai is East Africa’s most challenging one-day hike. The steep, volcanic terrain, night-time start, and high altitude test even experienced hikers — yet the rewards are unmatched.

Sunrise from the crater rim, overlooking Lake Natron
-
Active volcanic crater emitting steam and sulfur vents
-
Views of the Great Rift Valley and surrounding plains
-
