In terms of the technical aspects of ascending the mountain, Mount Kilimanjaro is not difficult to climb. Its slopes are mostly gentle, and its paths are well-trodden.
Trekkers can walk up to the summit without any expertise or mountaineering skills required. Tour operators organize climbs, while porters carry the gear, supplies and personal items.
Despite the relative ease on the technical side, many people find Mount Kilimanjaro very difficult to climb due to its high altitude. The difficulty varies from person to person and will depend upon how a trekker acclimatizes to the thin air at high elevations.
