Biobay, Vieques, Puerto Rico : Hidden along the Caribbean coast is one of the most spectacular Bioluminescent Bays in the world.

There are 3 bioluminescent bays in Puerto Rico, remember you're getting an excursion in Vieques Island.

The mysterious blue-green light is created by micro-organisms which thrive in an environment uniquely suited to their needs.

 A trip into the bay on a balmy night is a magical experience." - Captain Sharon Grasso This unique bay contains up to 720,000 single-celled bioluminescent dinoflagellates per gallon of water. These half-plant, half-animal organisms emit a flash of bluish light when agitated at night. The high concentration of these creatures (Pyrodimium bahamense) can create enough light to read a book from.

What you can do to preserve the Bioluminescent Bay

You can make a contribution to the preservation of the Bio Bay by doing a few simple things. Every one of us can do a little to ensure that our children and the next generations can enjoy this natural wonder.
  • Do not swim in the bio bay. It is against the law, responsible tour guides will not allow you to swim. Any chemicals you apply to your skin such as bug repellent, lotions, etc. will harm the ecosystem of the bio bay.
  • Only book tours with licensed approved tour operators. Tour guides that allow you to swim are breaking the law and not showing respect or love for the island, please do not go in the water just because they let you in, you can choose to protect the bio bay for future generations.
  • No trash or any objects on the Bio Bay – Please refrain from throwing any type of objects on the water during your tour. The smallest object, can or piece of trash can kill thousands of the precious little “dinos” that create this night show.
