Marangu Route is the oldest and most popular route. One time the route was dawning over 80% of trekkers on Kilimanjaro, as a result come to be known as coca cola route, this has led potential climber to think that it is an easy route to the summit but this it is not true. The fact is it requires a minimum of 5 or 6 days to complete. It is the only route up where you sleep in huts as opposed to tents. Due to this an advance booking of hut accommodation is required to avoid any inconveniences.
The trail goes through tropical rainforest, health and moorland zone to alpine desert then the arctic zone at the peak and same route down.
