Never swap Saturday morning and Sunday morning at the Central Market
Saturday between 09:30 and 13:30 is the busiest, most atmospheric window of the week at the Mercado Central de Abastos, when provincial produce, Sierra de Cádiz cheeses, and bay fish stalls are in full swing. On Sundays the traditional fish and produce stalls are shut, so keep Sunday morning for the Alameda, Iglesia del Carmen, and Plaza de Mina.
