Mosquito Bay (Vieques)
Mosquito Bay on the island of Vieques is a bioluminescent bay, which means the water glows in the dark. Tiny living creatures in the water light up bright blue whenever something moves through them.
It holds the world record as the brightest glowing bay on the planet, so it feels truly magical at night. Visitors love watching the water sparkle like liquid stars when they paddle through it.
Natural Wonder
The glow comes from millions of tiny microbes called dinoflagellates that make their own blue light. The bay is protected and cared for so it can keep shining brightly for years to come.
Activities
Guides take families out in kayaks or clear boats after dark to watch the water glow around them. Every paddle stroke leaves a trail of blue sparkles behind.
Best Time
The bay glows best on dark nights when the moon is small or hidden. Warm evenings make the trip comfortable, and the show is a wonderful surprise for first-time visitors.
