On Kilimanjaro, the amount of time spent hiking each day can vary depending on a few factors. Typically, most hikers will spend an average of 6-8 hours a day trekking up and down the mountain. The exact length of time that you hike each depends on your overall fitness level and how quickly you are able to ascend or descend the summit. Additionally, many guided tours limit their daily hikes to around 5-7 hours per day in order to prevent altitude sickness and exhaustion among climbers. Therefore, if you plan on climbing Kilimanjaro it is important to factor in these approximate durations when planning out your itinerary for the trip!
