Kilimanjaro is a free-standing volcano rising from farmland at around 900 metres to a glaciated summit at 5,895 metres. No technical climbing is involved on the standard routes: it is a long uphill walk through five distinct climate zones, from cultivated foothills and rainforest to heath, alpine desert and finally ice.
Altitude, terrain and weather all affect a climb. Gradual acclimatisation matters, but fitness does not prevent altitude illness and no duration guarantees a summit. Discuss the complete ascent profile and your health history with a qualified clinician before booking.
Routes differ in scenery, traffic and how well they let you climb high and sleep low. Lemosho and the Northern Circuit are the longest and gentlest; Machame is the most popular compromise; Rongai approaches from the drier northern side; Marangu uses huts rather than tents and, despite its reputation as the easy option, has one of the lower summit rates because it is short.
Every climb is supported by a licensed guide team, cooks and porters, and all climbers and crew are registered at park gates. Ethical operation matters here: fair porter loads, proper pay and mountain-appropriate kit for the crew are part of how a climb should be organised, not an optional extra.
