The 6-Day Umbwe Route has a well-deserved reputation as the most challenging route on Mount Kilimanjaro. Approaching from the south, it is a short, steep, and direct climb through rainforest and alpine terrain before joining the Southern Circuit to the summit. The descent follows the Mweka Route. Because of its steepness in the first two days and its short acclimatisation time, this route is considered very difficult and is best suited to strong hikers who are confident in their ability to acclimatise to the altitude.
