Bullfighting takes place late Sunday afternoons January through March in the Plaza de Toros at the end of "Caleta" bus routes. The ring has a shady and a sunny side though by 5:30 pm - when the action begins - most are in the shade. You can buy tickets at the ring starting at noon on fight day. General admission is only around 50 pesos ($3), but front row seats go for as much as 400 (around $25).
