Mosquito Bay

Mosquito Bay, located on Vieques Island in Puerto Rico, is famous for its extraordinary bioluminescent display. It’s one of the brightest bioluminescent bays in the world, caused by tiny microorganisms called dinoflagellates that emit light when disturbed. During the night, paddle strokes or other movements in the water make the bay glow with a mesmerizing blue light. This natural phenomenon results from a unique combination of environmental factors, including the bay’s calm, shallow waters and minimal light pollution. Visiting Mosquito Bay offers a spectacular, eco-friendly experience to witness nature’s living light show.
