Why El Alto
El Alto, known in Aymara as Patamarka and in Spanish as "The High One," is the second-largest city in Bolivia. Situated in Pedro Domingo Murillo Province on the high Altiplano plateau, it sits directly adjacent to La Paz. Situated at an elevation between 4,000 and 4,300 meters above sea level, it is considered the highest major city in the world. Together with La Paz and neighboring localities such as Achocalla, Viacha, and Mecapaca, it forms the nation's most populous metropolitan region.
Perched high above the canyon rim, El Alto experiences a cold subtropical highland climate shaped by high altitude and thin atmospheric cover. Daytime temperatures generally hover between 13 °C and 17 °C, with the warmest monthly highs occurring in November. Nighttime conditions regularly approach or drop below freezing, particularly in the winter, and snowfall can occur at any time during the year. The city's water supply is supplied by surrounding dams fed by glacial melt, leaving water availability vulnerable to mountain droughts.
The area initially served as a key overland route leading down to the valley floor. In October 1548, the Spanish commander Alonso de Mendoza paused at La Ceja on the plateau's edge to view the valley below, where the city of La Paz was subsequently established. The windswept plain remained largely unsettled until 1903, when railway lines arriving from Lake Titicaca and Arica established terminal yards along the rim. The opening of a military airfield in 1925, followed by the connection of piped water from La Paz in the 1950s, catalyzed rapid expansion. El Alto was politically separated from La Paz in March 1985 and officially incorporated as an independent city in 1987.
Modern El Alto has developed a unique urban identity characterized by vibrant Neo-Andean architecture, a style that began flourishing in the mid-2000s. Cultural points of interest include the Antonio Paredes Candia Art Museum, which opened its doors in 2002, alongside an extensive open-air market. Today, the municipal territory is officially organized into 14 administrative districts.
Travelers reach the city via El Alto International Airport, which provides domestic and international air connections. Transit between the high plateau of El Alto and central La Paz is facilitated by three lines of the Mi Teleférico aerial cable car network, offering direct, elevated transport down into the valley.
