The average summit success rate on Kilimanjaro has risen from about 50% to around 60% or higher. It varies depending on the route and length of the journey. The more time you spend on the mountain, the more likely you are to reach the peak. The average success rate has grown as the necessity of acclimatization has been more widely recognized. Climbers are increasingly opting for longer 7 or 8-day itineraries, which were once the most popular 5 or 6 day climbs. Assuming a decent level of fitness and average altitude tolerance, your summit success rate approaches 100% if you follow a route that is optimal for altitude acclimatization.
