The Guadalquivir is the fifth-longest river in the Iberian Peninsula and the second-longest river with its entire length in Spain. The Guadalquivir is the only major navigable river in Spain. Currently it is navigable from the Gulf of Cádiz to Seville, but in Roman times it was navigable to Córdoba.
The river is 657 km (408 mi) long and drains an area of about 58,000 km2 (22,000 sq mi). It rises at Cañada de las Fuentes (village of Quesada) in the Cazorla mountain range (Jaén), flows through Córdoba and Seville and reaches the sea at the fishing village of Bonanza, in Sanlúcar de Barrameda, flowing into the Gulf of Cádiz, in the Atlantic Ocean.
The river borders the Doñana National Park reserve.
