During the Bous a la Mar Festival, in Denia, near the city of Alicante, people get chased by bulls through the streets and into the Mediterranean Sea. The brave participants plunge into the waters just before the bulls are about to catch them. The animals often fall into the sea as well, where they are taunted some more. Eventually, the bulls are caught with a lasso and towed back to shore by a boat.
