How to acclimatize on Kilimanjaro
Acclimatisation is the body's adjustment to lower oxygen. It takes time, and the route you choose decides how much time you get.
Choose a longer route
Every extra day improves acclimatisation. Seven- and eight-day routes have much higher summit success than five- and six-day routes.
Climb high, sleep low
Routes such as Machame and Lemosho go up to Lava Tower (4,630 m) and down to Barranco (3,960 m) on the same day. This helps the body adapt.
Walk slowly
“Pole pole” (slowly, slowly) is not a slogan. Walking at a pace where you can talk comfortably reduces strain.
Drink and eat
Aim for 3 to 4 litres of water per day. Keep eating, even when your appetite drops.
Pre-acclimatise
Climbing Mount Meru (4,566 m) before Kilimanjaro is an excellent way to adapt. Some climbers also spend nights at altitude at home, but a real mountain works best.
Medication
Acetazolamide (Diamox) can help acclimatisation. Discuss it with your doctor before you travel.
Daily health checks
Guides check your oxygen saturation and pulse morning and evening, and ask about symptoms. Be honest. The information helps them keep you safe.
