Kilimanjaro is a walk, not a technical climb, which surprises people, but that does not make it easy. Altitude is the real challenge, not terrain or fitness in the conventional sense.

Route choice matters more than most people realise going in. Shorter routes like Marangu (five to six days) are cheaper but give your body less time to acclimatise, and success rates are noticeably lower as a result. Longer routes such as Lemosho or Machame, typically seven to eight days, cost more but give a much better chance of actually reaching the summit comfortably, because the extra days allow proper altitude adjustment. If budget allows any flexibility, choosing more days over fewer is the single best decision you can make.

Fitness helps, but it is not the deciding factor. Steady hikers with average fitness summit regularly, while very fit people who ascend too fast can still be turned back by altitude sickness. Pace, described by guides as “pole pole”, slowly slowly, is taken seriously for a reason.

Altitude sickness is the main real risk. Symptoms include headache, nausea and disturbed sleep, and mild versions are extremely common even in successful climbers. Guides monitor this closely and will turn people back if symptoms become severe, which is exactly what should happen. Discuss altitude sickness medication with a doctor before you go, as many climbers use it as a precaution.

Book with a reputable operator who provides proper crew welfare, since porter treatment on Kilimanjaro has been a genuine ethical issue in the industry. Ask directly about porter wages, load limits and equipment provided.
