The Umbwe Route on Kilimanjaro is probably the most dangerous of all routes. This is because it is incredibly steep, tough and very exposed in parts. On some parts of the trail, it is so steep that you have to rely on nearby tree routes to navigate your way across. It is also a very short route, so it does not give your body as much time to cope with the high altitude.
What compounds the potential dangers is that a few operators will even take you through the Western Breach on this route, which carries the risk of falling rocks and injury. Therefore, only experienced climbers that are accustomed to high altitude trekking should consider attempting this.
