Mount Kilimanjaro is the highest mountain in Africa and the tallest free-standing mountain in the world, rising 5,895 metres from the plains of northern Tanzania without a surrounding range to support it.
It is a dormant stratovolcano with three cones — Kibo, Mawenzi and Shira — and Uhuru Peak on Kibo’s crater rim is the summit. Uniquely among mountains of its height, it can be climbed without ropes or technical skill, which is why tens of thousands attempt it each year.
The ascent passes through five distinct ecological zones in a matter of days: cultivated farmland, montane rainforest, heath and moorland, alpine desert and finally the arctic summit zone, a compression of climate that has been compared to walking from the equator to the poles.
The glaciers on the summit have retreated dramatically over the past century and are widely expected to disappear within decades, which has become one of the most visible symbols of climate change in Africa.
