BioBay Boat and Swim

Bioluminescence is the production and emission of light by a living organism.

Imagine swimming in the glowing waters of one of only 12 BioBays in the world! Experience the bioluminescence up close! There is no other tour like it!

Cayman Sea Elements offers BioBay boat tours aboard our custom 35 ft pontoon boat  “Blue Horizons.”

Just a short hop from the Seven Mile Beach Area, our dock is located in the Cayman Islands Yacht Club. From there, you will enjoy a comfortable boat ride with your family and friends across the North Sound, experiencing the sunset on our way to the Bay and the starry skies on our return journey.

Once in the BioBay, our guides will share the story of why the microscopic, bioluminescent animals congregate there, and why they make this beautiful performance that we all enjoy.

Guests are welcomed to slip into the water to view the millions of these glowing creatures, and their mesmerizing, illumination show from underwater!

This is a snorkel you will never forget!

As one of our younger guests described it..  “Mommy, it is like all the stars fell into the ocean!”

This trip is NOT conducted during the fuller moon phases, as we need a dark sky for a great tour. Please see below for a schedule.

Suitable for all ages and mobility levels.

You are welcome to bring your own drinks and snacks,  “Adult” drinks are ok for the return trip.

We will supply snorkel equipment if you do not have your own. No fins please!

We have full rashguard suits available for those that would like to use one. We also have snorkel vests, “pool noodles” and plenty of other “floaty” things to make this a really relaxing and safe experience.

Don’t forget your towel!

Contact us for tour dates and times. Currently tour time is 7pm to 9:30pm.
