Vieques
With its quiet beaches and coral reefs, Vieques has become a popular destination for eco-tourism. The waters literally glow in the dark at Mosquito Bay, one of the brightest bioluminescent bays in the world. Tiny microorganisms called dinoflagellates create the mysterious blue-green light, which is best viewed on cloudy or moonless nights. Several companies provide guided tours of the bay, including Black Beard Sports, (787) 300-0155 and JAK Water Sports, (787) 644-7112.
The Punta Mulas Lighthouse, known as Morropó, has been protecting the port town of Isabel Segunda since 1893. Vieques lies about 8 miles off the eastern shore of Puerto Rico; daily ferries run from Fajardo, and air flights are available from Luis Muñoz Marin International Airport and also from the Isla Grande Airport in the Convention Center District.
