Cadiz ★ 4.4
Cadiz is the Atlantic port 90 minutes south of Seville with the Mercado Central seafood counters, the May atun rojo de almadraba trap-fishing season.
Tip: Visit the Mercado Central before 13:00 for the live tuna butchery in May; lunch at El Faro de Cadiz for the canonical Atlantic seafood plates.
