Bioluminescent Bay (aka Mosquito Bay or Puerto Mosquito) is one of Puerto Rico’s three bioluminescent bays, located on the island of Vieques. A popular destination for nighttime boat tours, this bay is by far the brightest. The water is illuminated by dinoflagellates called Pyrodinium bahamense, tiny microorganisms that glow when touched.

Awesome experience.
It was an amazing night. I didn't knew where to look, if up at the stars or below at the bay. The bay ended up winning. The glow is something out of this world. It's just amazing. The guide was incredible. Very flexible and we'll verse on the subject.

Must do atleast once in a lifetime
This was our first time at the bioluminescent bay and the location chosen by Lulu, our guide was spectacular. We got to see a lot of fishes. It was a starry night with no moon which enhanced our experience. Lulu was very friendly and gave a detailed tour. The whole experience was breathtaking and we’d definitely recommend this tour.

Billions of sparkly lights on the water!
Being asked to relax and experience the peaceful bay, seeing the fish move underwater and having a knowledgeable guide made it a very good experience.
