Vieques Island Attractions

Experience the beauty and magic of Mosquito Bay, the brightest bioluminescent bay in the world. The bio bay at Vieques Island is the area’s most popular attraction and is a must for anyone visiting Puerto Rico. Located at the southern shore of Vieques island, Mosquito Bay lights up at night with a blue glow from the half-plant, half-animal microorganisms that live below the water’s surface. The best time to experience this naturally occurring phenomenon is during a new moon, when there is less light emitted from the sky, making the microorganisms more visible.

While you cannot visit the bio bay Vieques unaccompanied, we suggest signing up for a tour. Here are a few tour companies in the area that provide tours and rentals.
