El Alto in the context of "Andes Mountains"

The Andes (/ˈændiːz/ AN-deez), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,500 mi) long and 200 to 700 km (120 to 430 mi) wide (widest between 18°S and 20°S latitude) and has an average height of about 4,000 m (13,000 ft). The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.

Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Arequipa, Bogotá, Cali, Medellín, El Alto, La Paz, Mérida, Santiago and Sucre. The Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.

La Paz (Spanish: [la ˈpas]; lit. 'the peace'), officially Nuestra Señora de La Paz (Aymara: Chuqi Yapu Aymara pronunciation: [ˈtʃoqɛ ˈjapʊ]), is the seat of government of Bolivia. With 755,732 residents as of 2024, it is the third-most populous city in Bolivia. Its metropolitan area, which includes the neighboring city of El Alto, and other smaller towns, is the second most populous urban area in Bolivia, with a population of 2.2 million, after Santa Cruz de la Sierra with a population of 2.3 million. The city is also the capital of the department of the same name.

Located in west-central Bolivia 68 km (42 mi) southeast of Lake Titicaca, La Paz is set in a canyon created by the Choqueyapu River. It is in a bowl-like depression, part of the Amazon basin, surrounded by the high mountains of the Altiplano. Overlooking the city is the triple-peaked Illimani. Its peaks are always snow-covered and can be seen from many parts of the city. At an elevation of roughly 3,650 m (11,975 ft) above sea level, La Paz is the highest administrative capital city in the world. Due to its altitude, the city has an unusual subtropical highland climate, with rainy summers and dry winters.

The Altiplano (Spanish for "high plain"), Collao (Quechua and Aymara: Qullaw, meaning "place of the Qulla") or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north–south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, its southwestern fringes lie in Chile, and it extends into Argentina.

Many towns and several cities are on the plateau, including El Alto and Oruro in Bolivia and Juliaca and Puno in Peru. The northeastern part of the Altiplano is more humid than the southwestern part, which has several salares (salt flats), due to its aridity. At the Bolivia–Peru border lies Lake Titicaca, the largest lake in South America. Farther south, in Bolivia, Lake Poopó existed until recently, but by December 2015, it had completely dried up, and was declared defunct. Whether that lake, which had been the second-largest in Bolivia, can be restored is unclear.

Pedro Domingo Murillo is a province in the Bolivian La Paz Department. It was created on January 8, 1838, with the name Cercado and on October 17, 1912, during the presidency of Eliodoro Villazón, its name was changed in honor of Pedro Domingo Murillo, protagonist of the revolution of June 16, 1809.

The province contains the Bolivian administrative capital, La Paz, as well as the major city of El Alto.

This list of the highest cities in the world includes only cities with a population greater than 100,000 inhabitants and an average height above sea level over 2,000 metres (6,600 ft).

Oruro (Hispanicized spelling) or Uru Uru is a city in Bolivia with a population of 264,683 (2012 calculation), about halfway between La Paz and Sucre in the Altiplano, approximately 3,709 meters (12,169 ft) above sea level.

It is Bolivia's fifth-largest city by population, after Santa Cruz de la Sierra, El Alto, La Paz, and Cochabamba. It is the capital of the Department of Oruro and the seat of the Roman Catholic Diocese of Oruro. Oruro has been subject to cycles of boom and bust owing to its dependence on the mining industry, notably tin, tungsten, silver and copper.
