Mosquito Bioluminescent Bay in Vieques, Puerto Rico

Is a bio bay on your bucket list for Puerto Rico?

Mosquito Bay in Vieques is known for being the brightest bioluminescent bay on the planet!

Located on the southern shore of Vieques, Mosquito Bioluminescent Bay makes for a magical experience when conditions are right.

So what exactly is a bioluminescent bay?

Bioluminescence is the emission of light by a living organism. Dinoflagellates, officially Pyrodinium bahamense, create the magical blue light at Mosquito Bay, one of three bio bays in Puerto Rico.

With each movement of your paddle through the water, you’ll see the light glimmer.

There are only five bio bays in the world, so it’s worth experiencing this unique phenomenon on your trip to Vieques!

Bioluminescence is best seen on moonless nights, so plan your trip for the new moon lunar phase.

Most visitors join a guided tour to experience the magic of bioluminescence.

On this highly-rated kayaking tour, you will paddle out in clear kayaks after dark under the direction of your guide and witness the gleaming blue light before heading back.
