Mountain Illimani

Illimani is the highest mountain in the Cordillera Real of western Bolivia. It lies near the cities of El Alto and La Paz at the eastern edge of the Altiplano. It is the second highest peak in Bolivia, after Nevado Sajama, and the eighteenth highest peak in South America. The snow line lies at about 4,570 metres above sea level, and glaciers are found on the northern face at 4,983 m. The mountain has four main peaks; the highest is the south summit, Nevado Illimani, which is a popular ascent for mountain climbers.

Geologically, Illimani is composed primarily of granodiorite, intruded during the Cenozoic era into the sedimentary rock, which forms the bulk of the Cordillera Real.Illimani is quite visible from the cities of El Alto and La Paz, and is their major landmark. The mountain has been the subject of many local songs, most importantly "Illimani", with the following refrain: "¡Illimani, Illimani, centinela tú eres de La Paz! ¡Illimani, Illimani, perla andina eres de Bolivia!"
