The Marangu route is also referred to as the "Coca-Cola" route, as it is considered to be the easiest path on the mountain, given its gradual slope and direct path. It is the oldest and the most well established route on the Kilimanjaro. This is the only route which offers sleeping huts in dormitory style. Guests are supplied with mattresses and pillows, but sleeping bags are still required. The huts have communal dining halls, basic washrooms and toilet. Short time frame of the route makes altitude acclimatization fairly difficult. 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.
