Which five traditional geographic regions make up Colombia?

Colombia is traditionally divided into five distinct geographic regions:1

• Atlantic lowlands: A region of coastal plains and river valleys that serves as a major center for agriculture and trade.1
• Pacific coastal region: A sparsely inhabited area characterized by lush rainforests and limited commercial activity.1
• Andean region: The center of the country's political and economic power, containing the majority of the population and major cities like Bogotá, Medellín, and Cali.1
• Llanos: A vast, grass-covered savanna complex located in the eastern part of the country, traditionally associated with cattle raising.1
• Amazonian rainforest: A remote, heavily forested region in the south that, together with the Llanos, comprises nearly two-thirds of Colombia's total land area.1
