Located in the North of South America (4 00 N, 72 00 W) and part of Caribbean South America. The only South American country with coast in both oceans (Atlantic or Caribbean Sea with 1,760 km and Pacific Ocean with 1,448 km. Borders: North with the Caribbean Sea (sea boaders with Jamaica, Haiti and Dominican Republic). West with Panama (225 km) and sea borders with Costa Rica both in the Pacific and Atlantic Ocean and Guatemala. South with Ecuador (590 km), Peru (1,496 km) and Brazil (1,643 km). East with Brazil and Venezuela (2,050 km).

Colombia has a total area of 1,138,910 km? being the fourth biggest country in South America after Brazil, Argentina and Peru and the seventh one in the American Continent. From this area, the land has 1,038,700 km? and the water area has 100,210 km?. It has also an archipelago in the Caribbean sea (San Andres, Providencia and Santa Catalina) that forms the territory of the department San Andres y Providencia.

Mainland territory divided into four major geographic regions: Andean highlands (composed of three mountain ranges and intervening valley lowlands); Caribbean lowlands; Pacific lowlands; and Ilanos and tropical rainforest of eastern Colombia. Colombia also possesses small islands in both Caribbean Sea and Pacific Ocean.

Striking variety in temperature resulting principally from differences in elevation; little seasonal variation. Habitable areas consist of hot (below 900 meters in elevation), temperate (between 900 and 1,980 meters), and cold (from 1,980 meters to about 3,500 meters) climatic zones. Precipitation generally moderate to heavy, with highest levels in Pacific lowlands and in parts of eastern Colombia; considerable year-to-year variations recorded.

The Andes range is located in Colombia from Southwest (Ecuador boarder) toward Northeast (Venezuela boarder) and is divided in the Colombian Massif (Macizo Colombiano) in three ranges (East Range, Centre Range and West Range) that form two long valleys, Magdalena and Cauca follow by the rivers of the same name. The highest mountain in Colombia is not in the Andes but in the Caribbean plain: Sierra Nevada de Santa Marta with its highest points named Pico Cristobal Colon (5,775 m) and Pico Simon Bolivar (same elevation).

The eastern part of Colombia, comprising more than half its territory, is plain and composed by savanna and rainforest, crossed by rivers belonging to the Amazon and Orinoco basins. The northern part, called "Los Llanos" is a savanna region, mostly in the Orinoco basin (therefore called also Orinoquia). The southern part, usually called Amazonia, is covered by the Amazon rain forest and belongs mostly to the Amazon basin.

At the north and west of the Andes there are coastal plains, the Caribbean plains to the north and the Pacific plains to the west.

Colombian Pacific plains are among the most rainy parts in the world, especially at the north (Choco).

The five traditional natural regions are therefore: the Andean Region, the Caribbean Region, the Pacific Region, the Orinoquia Region and the Amazonia Region. Some people also include an Insular Region, separated from the coastal regions.
