The Marangu route, also called “Coca-Cola" route, is the oldest and well established route on Kilimanjaro. The route approaches Mount Kilimanjaro from the southeast. Marangu is unfortunately less scenic than the other routes because the ascent and descent are along the same path. It is also the most crowded route for that reason.
It is considered to be the easiest path on the mountain, given its gradual slope and direct path.
One of the interesting aspects of Marangu Route is that it is the only route up Mount Kilimanjaro that doesn’t allow camping, so instead of sleeping in tents, trekkers stay in permanent huts.
