Geography

Main article: Geography of Colombia See also: Natural regions of Colombia and Geology of Colombia

The geography of Colombia is characterized by its five main natural regions that present their own unique characteristics, from the Andes mountain range region shared with Ecuador and Venezuela; the Pacific coastal region shared with Panama and Ecuador; the Caribbean Sea coastal region shared with Venezuela and Panama; the Llanos (plains) shared with Venezuela; to the Amazon Rainforest region shared with Venezuela, Brazil, Peru and Ecuador. Colombia is the only South American country which borders both the Atlantic and Pacific Oceans.

Colombia is bordered to the east by Venezuela and Brazil; to the south by Ecuador and Peru; to the north by Panama and the Caribbean Sea; and to the west by Ecuador and the Pacific Ocean. Including its Caribbean islands, it lies between latitudes 14°N and 5°S, and longitudes 66° and 82°W

Part of the Ring of Fire, a region of the world subject to earthquakes and volcanic eruptions, Colombia is dominated by the Andes (which contain the majority of the country's urban centres). Beyond the Colombian Massif (in the south-western departments of Cauca and Nariño) these are divided into three branches known as cordilleras (mountain ranges): the Cordillera Occidental, running adjacent to the Pacific coast and including the city of Cali; the Cordillera Central, running between the Cauca and Magdalena river valleys (to the west and east respectively) and including the cities of Medellín, Manizales, Pereira and Armenia; and the Cordillera Oriental, extending north east to the Guajira Peninsula and including Bogotá, Bucaramanga and Cúcuta. Peaks in the Cordillera Occidental exceed 13,000 ft (3,962 m), and in the Cordillera Central and Cordillera Oriental they reach 18,000 ft (5,486 m). At 8,500 ft (2,591 m), Bogotá is the highest city of its size in the world.

East of the Andes lies the savanna of the Llanos, part of the Orinoco River basin, and, in the far south east, the jungle of the Amazon rainforest. Together these lowlands comprise over half Colombia's territory, but they contain less than 3% of the population. To the north the Caribbean coast, home to 20% of the population and the location of the major port cities of Barranquilla and Cartagena, generally consists of low-lying plains, but it also contains the Sierra Nevada de Santa Marta mountain range, which includes the country's tallest peaks (Pico Cristóbal Colón and Pico Simón Bolívar), and the Guajira Desert. By contrast the narrow and discontinuous Pacific coastal lowlands, backed by the Serranía de Baudó mountains, are sparsely populated and covered in dense vegetation. The principal Pacific port is Buenaventura.

Colombian territory also includes a number of Caribbean and Pacific islands. This is considered by some as a sixth region, comprising those areas outside continental Colombia, including the department of San Andrés y Providencia in the Caribbean Sea and the islands of Malpelo and Gorgona in the Pacific Ocean. However, cultural ties are with the respective coastlines. In this region Colombia has a lot of stable sand banks of considerable size, considered suitable for the development of artificial islands.
