What Is Bioluminescence?

Defined as “life emitting light,” bioluminescence is a beautiful part of nature. The creature or organism produces this light by releasing energy from chemical reactions inside or outside their body. While commonly found in the ocean, the high concentration of bioluminescent plankton, known as dinoflagellates, in the Cayman Islands is extremely rare. There are only 12 locations in the entire world! Because the bioluminescent organisms are so small here, it seems as if the water itself is lighting up.

How to Explore the Bioluminescent Bay in Grand Cayman

George’s Watersports

Hop on the boat to Bio Bay, then choose if you’d like to snorkel or stay in the boat. We highly recommend snorkeling; all gear is provided, and you’ll have a much better view of the gorgeous water! When you go underwater with your mask and move around, you will have much better visibility.

After, you are welcome to get into the water and explore for yourself. Snorkel gear is provided and you are more than welcome to bring refreshments to enjoy!
