This is the standard and best-documented ascent line on Cerro Marmolejo. It is generally climbed as a high-altitude snow-and-rock mountaineering route rather than a technical alpine climb. The route is long and strenuous because of the mountain's great elevation and the dry, exposed environment of the central Andes. Objective hazards include altitude, cold, wind, and possible snow or ice on the upper mountain. Route-finding is usually straightforward compared with more technical peaks, but conditions can vary significantly. It is the established summit route referenced by most climbing accounts for this peak.
