I did this in 2022, and it was really cool! Heading out to the bay in the night after dark, we could already see the water light up around the boats in the area.

And as I got in myself, it was even brighter, like swimming in a blue-lit pool where you can’t see where the lights are!

As you arrive with the boat in the bay, it will turn off all the lights, and you can see how the boat stirs up the light in the water before it comes to a halt.

What Is Bioluminescent Water?

Grand Cayman Bioluminescence Tour
Can hardly see that it is me!!

Bioluminescence is the term used to describe the glowing lights found in the waters and shores of the ocean caused by living organisms emitting a biochemical light!


The blue light that occurs shines when the microorganisms are “disturbed# in the water, by a boat, by a swimmer, or snorkeled making movement with our hands and feet which creates a beautiful sparkling and shining blue effect in the water.

And this particular tour in Grand Cayman has an average of 5 stars with over 700 reviews!
