Cerro El Plomo is a mountain in the Andes near Santiago, Chile. With an elevation of 5,434 m (17,783 ft), it is the largest peak visible from Santiago on clear days. The adequate season to climb this mountain is between November and March. In spring (September to November), soil conditions have abundant snow on the approach. The best time is in January and March, where the approach is snow free, except for some specific areas, and the climate is more stable. The Incas climbed to its summit periodically in the 15th century. The first European ascent of the mountain was by Gustav Brandt and Rudolph Lucke in 1896.
