Marangu Route, popularly called “Coca-Cola Route”, is the most renowned route to trek Kilimanjaro. Marangu is the only route that provides sleeping in huts, all the way to Uhuru Peak, contrary to all other routes where you get to sleep in tents/sleeping bags. The route is very steady, with gradual slopes, but it is far from easy. It has a very low success rate, because trackers tend to not take it seriously, due to its reputation to be “Tourists Route”.
You do not need camping gear while trekking Marangu, but by all means you need to be physically prepared for the climb, otherwise there is a good chance for dropping out before reaching the top.
The route is offered at 5 or 6 days, but note that on shorter plan you do not have a day for acclimatization, which is usually necessary to accommodate high altitude conditions. Descend is at Marangu gate.
