Climbing Mount Kilimanjaro typically takes a minimum of five days, but most successful expeditions last between six and eight days. Longer itineraries significantly improve acclimatization, which is essential for coping with the altitude and increasing the chances of reaching the summit. Extended routes, some lasting ten days or more and including options like an overnight stay in the crater, offer climbers a more gradual ascent and a richer experience. Choosing a well-paced route with a strong acclimatization plan can lead to a summit success rate as high as 98.5%, making it a key factor in a safe and successful climb.
