Lima - Geography

Geography

The urban area of Lima covers about 800 km2 (310 sq mi). It is located on mostly flat terrain in the Peruvian coastal plain, within the valleys of the Chillón, Rímac and Lurín rivers. The city slopes gently from the shores of the Pacific Ocean into valleys and mountain slopes located as high as 500 metres (1,600 ft) above mean sea level. Within the city there are isolated hills which are not connected to the surrounding hill chains, such as El Agustino, San Cosme, El Pino, La Milla, Muleria and Pro hills. The San Cristobal hill in the Rimac district, which lies directly north of the downtown area, is the local extreme of an Andean hill outgrowth.

Metropolitan Lima has an area of 2,672.28 km2 (1,031.77 sq mi), of which 825.88 km2 (318.87 sq mi) (31%) comprise the actual city and 1,846.40 km2 (712.90 sq mi) (69%) the city outskirts. The urban area extends around 60 km (37 mi) from north to south and around 30 km (19 mi) from west to east. The city center is located 15 km (9.3 mi) inland at the shore of the Rimac river, a vital resource for the city, since it carries what will become drinking water for its inhabitants and fuels the hydroelectric dams that provide electricity to the area. While no official administrative definition for the city exists, it is usually considered to be composed of the central 30 out of the 43 districts of Lima Province, corresponding to an urban area centered around the historic Cercado de Lima district. The city is the core of the Lima Metropolitan Area, one of the ten largest metropolitan areas in the Americas. Lima is the second largest city in the world located in a desert, after Cairo, Egypt.
