It is one of the world's most accessible high summits, a beacon for visitors from around the world. Most climbers reach the crater rim with little more than a walking stick, proper clothing and determination.
But there is so much more to Kili than her summit. The ascent of the slopes is a virtual climatic world tour, from the tropics to the Arctic.
Even before you cross the national park boundary (at the 2,700m contour), the cultivated footslopes give way to lush montane forest, inhabited by elusive elephant, leopard, buffalo, the endangered Abbot's duiker, and other small antelope and primates. Higher still lies the moorland zone, where a cover of giant heather is studded with otherworldly giant lobelias.
