When Mount Meru exploded into life over 500,000 years ago, its entire eastern flank was blown apart by the explosion, giving the volcano its distinctive horseshoe rim. In addition to being the fourth largest mountain in Africa, Mount Meru’s rim extends 1,500 meters (4921 ft.) to the crater floor, making it one of the tallest cliffs in the continent as well.
Due to the abundance of wildlife on and around Meru, it is compulsory that visitors be accompanied by armed rangers. There is only one official route to the summit of Mount Meru, called the ‘Momella route’. Although it is optional to do the climb in 3 days (8.7mi), the more popular, 4 day (11.8 mi.) option is outlined in depth.
