Mount Kilimanjaro does not require technical mountaineering skills, yet over 30% of climbers fail to reach the summit. The leading cause of failure is acute mountain sickness (AMS) due to rapid ascents. Let's look at the success rates of each route.
Success rates on Mount Kilimanjaro are directly proportional to the number of days spent on the mountain. More days allow your body to produce more red blood cells, naturally adapting to the lower oxygen levels.

Three Secrets to Reaching Uhuru Peak
- Choose an 8-Day Route: Avoid short 5 or 6-day climbs. The extra expense of an 8-day Lemosho climb is worth the massive increase in success and safety.
- Walk 'Pole Pole' (Slowly): Listen to your Tanzanian guides. Walking extremely slowly saves energy and prevents altitude sickness.
- Drink 4-5 Liters of Water Daily: Hydration is critical to thinning the blood and aiding oxygen delivery.
