Gulf of Cádiz

The Gulf of Cádiz is the arm of the Atlantic Ocean between Cabo de Santa Maria, the southernmost point of mainland Portugal; and Cape Trafalgar on the Spanish coast at the western end of the Strait of Gibraltar. Two major rivers, the Guadalquivir and the Guadiana, as well as smaller rivers, like the Odiel, the Tinto, and the Guadalete, reach the ocean here.
