I certainly don't advocate you try your hand at this! But if there is a bullfight on at The Plaza de Toros in Mijas Pueblo or at the Estepona Bull ring, and you are interested in Spanish tradition, it may well be worth a visit ..... and yes there is blood and they do kill the bulls. Not my idea of an afternoon out, but each to their own.
Bullfighting remains today as popular as ever in Andalucia, in fact it is gaining not losing popularity!
