Kilimanjaro National Park, a UNESCO World Heritage Site encompassing 1,688 km² around Africa’s highest peak at 5,895 m, delivers a “world in one mountain” trek from equatorial rainforest to arctic summit. Located 300 km south of the equator and 50 km from Arusha, the park protects Mount Kilimanjaro’s three volcanic cones—Shira (extinct), Mawenzi (dormant), and Kibo (dormant with fumaroles). Vegetation belts ascend in perfect succession: cultivated foothills (800–1,800 m) give way to dense montane rainforest (1,800–2,800 m) dripping with moss and giant heather; heath and moorland (2,800–4,000 m) feature lobelia decks and everlasting flowers; alpine desert (4,000–5,000 m) hosts hardy lichens; and the glacial summit zone (above 5,000 m) holds permanent ice fields shrinking due to climate change.
Weather on Kilimanjaro varies by altitude and season: climbers target the dry windows of January–February and June–October for 20–25°C (68–77°F) at base and –10°C (14°F) at the summit with minimal precipitation. Short rains (November–December) bring afternoon showers below 3,000 m, while the long wet season (March–May) delivers heavy cloud and snow above 4,000 m, often closing routes. Night temperatures plummet year-round, demanding layered clothing and summit gloves.
Geologically, Kilimanjaro is a stratovolcano formed 750,000 years ago through rift-related eruptions; Kibo’s Reusch Crater still emits sulfurous gases from inner vents, and the Ash Pit reveals 400 m of layered lava. Glaciers like Rebmann and Furtwängler calve dramatically, while radial valleys (barrancos) carved by ancient lava flows guide trekking routes. Seismic monitoring confirms minor activity, but no eruptions since 360,000 years ago.
Wildlife adapts to altitude: blue monkeys, black-and-white colobus, and olive baboons forage in the rainforest alongside bushbabies and tree hyrax. Higher up, eland, Abbott’s duiker, and four-striped mice appear in moorland, with white-necked ravens and alpine chats circling the summit. No large predators roam the upper zones, enabling safe hiking.
Over 180 bird species reside across zones. Rainforest hosts silvery-cheeked hornbills, tropical boubou, and Hartlaub’s turaco; moorland shelters scarlet-tufted malachite sunbirds and hunter’s cisticola. Raptors include bearded vultures and Verreaux’s eagles. Migratory Palearctic species—Eurasian bee-eaters, willow warblers, and lesser kestrels—pass November–April, using lower slopes as stopover fuel.
