Lemosho route is one of the quietest route on the mountain and begins from the western side of the mountain; the trail passes through some of the mountains finest features, including the cloud forest of Kilimanjaro's southern plains, the dry and dusty Shira Plateau and the delightful groundsel-clad Barranco Camp site.
Curiously, though the Lemosho route is widely reckoned to be that much harder than most of the other routes as the walk up to the plateau is an exhausting one but a useful one for acclimatization. The proportion of trekkers who reach the top using this route is marginally but significantly higher. This could be down to a number of factors: the Lemosho route allows people to acclimatize better because it's longer (46.26km to the summit via Barafu, or 36.7km via the Western Breach as opposed to 35.5 km on Marangu route).
When it comes to climbing the slopes of Kibo, the Barafu route is more straightforward than the route from Kibo Huts to Gillman's, as it is largely conducted on the firm terrain of a ridge than sliding, shifting shale; or maybe the Lemosho's higher success rate is merely an indication that more experienced, hardened trekkers that is the very people who are most likely to reach the summit are more inclined to choose this route.
