Mount Ol Doinyo Lengai, meaning “Mountain of God” in the Maasai language, is an active stratovolcano in northern Tanzania. Rising to an elevation of 2,962 meters (9,718 feet), it is the only active carbonatite volcano in the world, creating unique white lava flows that harden into a striking landscape. This tour is perfect for adventure seekers looking to challenge themselves with a demanding overnight trek while experiencing breathtaking views of the Great Rift Valley, Lake Natron, and the surrounding Maasai land.

The climb is steep, challenging, and requires good physical fitness, but the reward at the summit—a surreal sunrise over a smoking crater—is an unforgettable experience. The trek is typically done at night to avoid the intense daytime heat, allowing climbers to witness a magical sunrise at the peak.
