Arecibo Lighthouse and Historical Park is off Hwy. 22 exit 71 (Domingo Ruiz), following Rd. 2 to Rds. 681 and 655. The park offers five cultural representations of Puerto Rico's history, from the 1493 Spanish Conquest to the building of the lighthouse in 1898 during the Spanish-American War. Historic replicas include a Taíno Indian village, slave quarters, Blackbeard's pirate ship and the three sailing vessels of Christopher Columbus. Marine artifacts are displayed in the restored lighthouse. The surrounding park on rocky Punta Morillo includes a playground; a small petting zoo; a miniature water park; and a pirate's cave containing a saltwater aquarium with sharks, rays and eels.
