The Marangu or main route is by far the most popular way to the summit. The ascent is more gradual and no professional equipment is required. The accommodation on the way up and down is provided in mountain huts with all the basic necessities. There are 60 bunk beds each (for 60 people each) at Mandara Hut (2700m) and Kibo Hut (4700m), and 120 bunk beds (for 120 people) at Horombo Hut (3720m) which is also used for descent. Climbers are supplied with mattresses and pillows, but sleeping bags should be brought along. There are communal dining halls, washrooms and toilets.
It usually takes 5 days/4nights for the round trip. The trek can also be taken in 6 days/5 nights to add acclimatization with an extra day at Horombo Hut. The supplementary cost for an extra day is indicated separately as an option.
