Celebrated every 3rd Saturday of January. This spectacular & exciting event find its origin on a hillside in one of the inland barangays of the municipality when resting farmers witness for the first time the fight between the two raging bulls, set loose by their herdsmen. It caught the fancy of the barangay folks and soon it became a popular entertainment in most barangay fiestas. During the municipal fiesta, the best bulls from different barangays are pitted against each other by weight category in a “Bull Derby”.
