There's a bullring (Plaza de Toros) on Rafael Buelna about 1.5km (1 mile) from the Zona Dorada. From December to early April, bullfights take place certain Sundays and holidays at 4pm; locals recommend arriving by 3pm. Tickets range from 100 pesos for general admission (ask for the shady side -- la sombra) to 300 pesos for the front of the shaded section; most travel agencies and tour desks sell advance tickets. Note that the bulls are killed in these events.
At Playa Olas Altas, daring cliff divers take to the rock ledges of El Mirador and plunge into the shallow, pounding surf below, a la Acapulco. The divers perform sporadically during the day as tour buses arrive near their perch, sometimes diving with torches on Sundays at 7pm. Follow the malecón to the esplanade and look for the mermaid statue to find El Mirador.
