How to do?
1. You can hear glowing lava roaring at the top of Ol Doinyo Lengai crater that is placed in the Ngorongoro Conservation Area, south-westward from Natron Lake. Climbing usually starts at midnight to reach the top at dawn. Trekking is pretty difficult and takes 7-12 hours depending on your fitness level - go to the crater only with a guide (group excursions starts from Arusha).
2. The path to the top is quite steep, so you'd better take a break in every 100 meters. Closer to the top you can stop to have breakfast. Heaving reached the edge of the crater at a height of 2960 meters, you'll finally hear lava moving inside eruptive vent. While you're listening, the sun is rising over Savannah - take a look at probably the most stunning natural phenomenon in Africa.
