Ol Doinyo Lengaï, meaning "Mountain of God" is a sacred place for the Maasai. The sense of its deity can be felt at the summit, as one looks down at the two craters. One of the craters is still active and last erupted in 1983.
The ascension of the circular crater (500m in diameter) is carried out accompanied by a Maasai guide and can be undertaken by anyone in good physical condition who does not suffer any respiratory problems.
The trek begins early in the morning to avoid the high temperatures during the day. There is a magnificent panoramic view from the summit.
