aquatic sports. One popular cruise is from Caletilla Beach to Roqueta Island, which has places to snorkel, have lunch, and a lighthouse. There is also an underwater statue of the Virgin of Guadalupe here, created in 1958 by Armando Quesado in memory of a group of divers who died here. Many of the scuba-diving tours come to this area as well, where there are sunken ships, sea mountains, and cave rock formations. Another popular activity is deep-sea fishing. The major attraction is sail fishing. Fish caught here have weighed between 89 and 200 pounds. Sailfish are so plentiful that boat captains have been known to bet with a potential customer that if he does not catch anything, the trip is free.

Parts of the moats remain as well as the five bulwarks and the battlements. Today the fort serves as the Museo Histórico de Acapulco (Acapulco Historical Museum), which shows the port's history from the pre-Hispanic period until independence.

Another place that is popular with children is the Parque Papagayo: a large family park which has a life-sized replica of a Spanish galleon, three artificial lakes, an
