Colombia

The Andes Mountains run north through western Colombia, where they divide into three parallel mountain ranges: the Western, Central, and Eastern ranges. Between them lie the broad valleys of the Cauca and Magdalena rivers. For centuries, those valleys offered easier places to farm, travel, and build towns, while the steep mountains made journeys from one region to another much harder.

Colombia is the only country in South America with coastlines on both the Caribbean Sea and the Pacific Ocean, and the two coasts feel very different. On the warmer, drier Caribbean side, ports such as Cartagena connected Colombia to ships carrying people and goods around the Caribbean and across the Atlantic. On the Pacific side, mountains rise close to the coast and some of the heaviest rainfall on Earth feeds dense rainforest, so many communities are still reached more easily by river or boat than by road.

Eastern and southern Colombia contain huge tropical lowlands. In the south and southeast, Amazon rainforest stretches across a maze of rivers and dense forest. Farther northeast, enormous tropical grasslands called the Llanos extend toward Venezuela. During the rainy months, rivers spill across the Llanos and turn large areas into shallow wetlands; in the dry season, the water retreats and grasslands return, supporting capybaras, anacondas, giant anteaters, and huge flocks of birds.

Colombia stretches from hot tropical lowlands to cold, wet mountain environments high in the Andes. Near sea level, the coasts and low valleys stay warm, while Bogotá sits about 2,600 meters (8,500 feet) above sea level and remains cool throughout the year. At the highest elevations are treeless, misty landscapes called páramos, where unusual plants such as giant rosette-shaped frailejones grow. In one country, a climb in elevation can take you from tropical heat to cool mountain cities to near-freezing highlands.

The Andes divide western Colombia into separate mountain ranges and valleys, making travel between regions difficult. As a result, several major cities grew in different pockets of flat land between the mountains: Bogotá on a high plateau, Medellín in a narrow valley, and Cali beside the broad Cauca River valley. For much of Colombia's history, those mountain barriers kept the cities relatively separated, helping each develop its own regional identity.

For centuries, steep mountains, rainforest, and long distances made travel between many parts of Colombia difficult, so regional cultures developed in relative isolation. On the Caribbean coast, cumbia—a lively music and dance tradition built around drums, flutes, and rhythmic movement—grew from the mixing of African, Indigenous, and Spanish traditions during the colonial period. On the eastern plains, generations of cattle ranching created a horseback culture shared with neighboring Venezuela, along with joropo, a fast-moving style of music and dance traditionally accompanied by harp, small guitar, and maracas.

Colombia's Indigenous nations have homelands in dramatically different parts of the country, from Caribbean desert to Andean mountains and Amazon rainforest. The Wayuu live on the dry La Guajira Peninsula along the Caribbean coast, the Nasa live in the Andean mountains and valleys of southwestern Colombia, and many other peoples live along rivers in the Amazon. Colombia legally recognizes many Indigenous territories, called resguardos, where communities hold land collectively and govern many local matters through their own authorities.

During Spanish colonial rule, enslaved Africans were brought to Colombia in large numbers to work in gold mines, ports, farms, and households. Many were taken to the Pacific and Caribbean regions, and along the extremely rainy, forested Pacific coast, mining settlements and communities grew beside rivers that served as the main routes through the rainforest. After slavery was abolished in 1851, freed people and their descendants continued living in communities along the Pacific and Caribbean coasts. Today, many Afro-Colombian communities along the Pacific live beside rivers and the sea, where boats remain essential for travel and fishing, music, and food traditions are closely tied to the water.

Colombia's coffee farms climb steep Andean mountainsides where large harvesting machines often cannot go. The country's tropical location allows coffee to grow year-round, while the cooler temperatures at higher elevations help the cherries ripen slowly. Because of the steep terrain, much of the crop is picked by hand, and generations of farming families have built towns and livelihoods around coffee.

High in the Andes around Bogotá, cool temperatures and strong equatorial sunlight create nearly ideal conditions for growing flowers year-round. Large greenhouses across the broad plateau produce roses, carnations, and other cut flowers, many of them bound for North America. Because the farms sit close to Bogotá's international airport, flowers that were growing in Colombia only days earlier can arrive in stores in time for holidays such as Valentine's Day.

Steep Andean mountains made overland travel through Colombia difficult for centuries, so the Magdalena River became the country's great north-south highway. Flowing from the interior toward the Caribbean Sea, it carried people, coffee, tobacco, and other goods between inland towns and coastal ports. Long before modern highways crossed the mountains, riverboats helped connect otherwise separated regions and helped towns grow along the riverbanks.

Emeralds are green crystals of a mineral called beryl, and some of the world's richest deposits formed deep inside Colombia's Eastern Andes. Hot, mineral-rich water moved through cracks in the mountain rock and cooled there, allowing emerald crystals to grow. Indigenous peoples, including the Muzo, mined and traded emeralds for centuries, and the region remains one of the world's best-known sources today.
