capital of Vichada departamento, eastern Colombia, situated at the junction of the Meta and Orinoco rivers, across from Puerto Páez, Venezuela. The easternmost of Colombia's urban centres and a potentially important port on the Orinoco River, the city is a collection centre for the cattle and livestock products, corn (maize), gums, and resins that are produced in the surrounding Llanos (plains). Puerto Carreño is accessible by highway from Villavicencio, the capital of Meta department, situated about 500 miles (800 km) to the west-southwest. Travel in the area, however, is by river or air.
