For the Marangu Route, it’s recommended to allow 6 days if possible, as the 5-day itinerary is shorter and makes acclimatization more difficult, while a longer trek improves summit success. Pace yourself along the steady trail to adjust to altitude, and take advantage of the hut accommodations to rest well without carrying heavy camping gear. Pack layers to handle temperatures ranging from warm rainforest days to freezing summit nights, and stay hydrated and eat regularly to maintain energy. Always go with a licensed guide for safety, guidance, and route knowledge, and prepare physically with endurance training even though moderate fitness is sufficient. Finally, respect the environment by sticking to trails and following hut and park rules.
