The La Guajira Desert is a desert located in northern Colombia and Venezuela, approximately 1,100 km (680 mi) north of Bogotá, covering most of the La Guajira Peninsula at the northernmost tip of South America. Most of the region is within Colombia's La Guajira Department, though a small portion is in Venezuelan territory. The area holds immense coal reserves which are exploited in a zone known as El Cerrejón. It is also home to the indigenous Wayuu people. The Wayuu are mostly herders but also master deep-sea divers, known for collecting pearls from the Caribbean Sea.
