The Umbwe route is a short, steep and direct route. It is considered to be very difficult and is the most challenging way up Mount Kilimanjaro. Due to the quick ascent, Umbwe does not provide the necessary stages for altitude acclimatization. Although the traffic on this route is very low, the chances of success are also low.
The route is offered at a minimum of six days, though seven days is recommended when attempting this route.
The Umbwe route should only be attempted by those who are very strong hikers and are confident in their ability to acclimatize.
