Kilimanjaro Mountain

Mount Ol Doinyo Lengai Active Volcano Trek

Experience an otherworldly adventure climbing Mount Ol Doinyo Lengai, rising 2,962 meters (9,718 feet) above the Great Rift Valley in northern Tanzania. Known as the "Mountain of God" in the native Maasai language, Ol Doinyo Lengai is the planet's only active natrocarbonatite volcano, producing a rare, highly fluid black lava that turns ash-white upon cooling. Located near the pink-hued shores of Lake Natron, this steep stratovolcano offers one of East Africa's most thrill-packed night climbs. Trekkers begin their ascent under a blanket of stars to reach the smoking crater rim by sunrise, witnessing jaw-dropping views across the Rift Valley escarpments, Ngorongoro Highlands, and distant views of Mount Kilimanjaro and Mount Meru.

Why Trek Ol Doinyo Lengai

Climbing Ol Doinyo Lengai is a steep and intense adventure that rewards brave hikers with a truly surreal, moon-like volcanic landscape. Navigating loose ash and rocky ridges alongside local Maasai guides, you will gain almost 1,800 meters of elevation in a single 5 to 7 hour push to the crater rim. Beyond the thrill of standing atop an active volcano crater, your itinerary easily pairs with visits to Lake Natron's massive breeding grounds for millions of lesser flamingos, refreshing swims at the lush Engaresero Waterfalls, and authentic Maasai cultural walking safaris.
