Kilimanjaro is the highest mountain in Africa, situated in north-eastern Tanzania between the town of Moshi and the Kenyan border.

Kilimanjaro is actually composed of three separate extinct volcanoes, believed to be last significantly active during the Pleistocene era. The smallest of the three craters is Shira at 12,999 feet. Next comes Mawenzi at 16,893 feet and then the highest, Kibo, at 19,341 feet. The summit crater at Kibo measures an awe-inspiring 1.5 miles across and is connected to the Mawenzi summit by an 11 mile wide saddle. Although Kilimanjaro lies 3° south of the equator, an ice cap covers the crater of Kibo year-round.
