Ol Doinyo Lengai, often called the "Mountain of God," is an active volcano located in northern Tanzania and is a must-visit for adventurous travelers. Towering over the Great Rift Valley, this majestic peak is unique due to its lava composition. Unlike most volcanoes that produce molten lava, Ol Doinyo Lengai emits natrocarbonatite lava, which is unusually cool and flows like water. This rare phenomenon makes it one of the most intriguing volcanic landscapes on Earth.
