It is located in southern Spain, in the region of Andalusia. Its coastline is part of the Costa de la Luz (Coast of Light) and features numerous golden sandy beaches, including everything from beaches in urban areas to extensive, practically unspoilt stretches of sand. In the interior, the popular White Villages Route is highly recommended.

It has three festivals of International Tourist Interest: the prestigious Carnival of Cadiz, the unique horse racing events on the beach at Sanlúcar de Barrameda, and the elegant Horse Fair in Jerez de la Frontera. Part of the province also lies within the Doñana National Park, and there are also another five nature reserves in Cadiz's exceptional natural environment.

Cadiz is also known for its delicious gastronomy, and particularly for its “pescaíto frito” (perfectly-fried platters of assorted fresh fish) and shellfish, ideally accompanied by the wines to be found on the Wine and Brandy routes in the Marco de Jerez region.
