As the tallest mountain in Africa—and the continent’s contribution to the “Seven Summits”— Kilimanjaro consists of three extinct volcanoes. Climbing more than 16,000 feet from the surrounding plains brings you through a stunning array of ecosystems: from cultivated soil, through rainforest, past alpine desert and up over glaciers at the peak. While this tough trek is well known as beginner-level, and most guide services require no prior experience, around 10 people still die on it each year, mostly from severe altitude sickness.
