AAA Editor Notes
La Parguera Bioluminescent Bay is 5 mi. (8 km) s. on the harbor. La Parguera is one of three bioluminescent bays in Puerto Rico; the others are found at Las Cabezas de San Juan Nature Preserve in Fajardo and at Mosquito Bay off the island of Vieques. The eerie blue-green light is produced by microorganisms that cause the water to shimmer and glow when disturbed.
