About this experience

There are only a handful of bioluminescence or bioluminescent bays in the Caribbean, and not many more than that in the world. They only occur in certain places because they only happen naturally under very specific conditions.

The water in Bio Bay is very warm and salty with an abundance of nutrients and seagrass, the perfect environment for special microscopic plankton. These plankton occur all over the island, and all over the Caribbean, but the concentration we find in Bio Bay is what makes for a fantastic experience. Because of these plankton “bioluminescence,” it produces a very short burst of light when stimulated by movement.

The Bio Bay is best viewed by floating in the water. With snorkeling gear, you’ll float in this magical bay mesmerized as your movements create trails of light in the water. This shimmering light show is awesome, and if the timing and conditions are right, you might even see the mating glow worms which occur two to three days after the full moon.
