The Guadalquivir is the fifth longest river in the Iberian Peninsula and the second longest river with its entire length in Spain.
The Guadalquivir river is the only great navigable river in Spain and is currently navigable from the Gulf of Cádiz to Seville, but in Roman times it was navigable all the way to Córdoba.
Cruising the Guadalquivir is an unusual European River Cruise in that you will normally spend a few hours on the ocean, traversing from Spain to Portugal.
It's a great destination for discovering the great Andalucian cities of Seville, Grenada and Cordoba, alongside Cadiz and the Algarve.
