Glow baby glow! - This was such an amazing experience. Everyone should do this at least once. They take you out on a boat to see the starfish then, once it gets dark, they take you to the bioluminescent bay, where the microscopic plankton glow. You have to move around in the water to see it glow but it’s really cool!

Wonderful - This tour was very easy to enjoy. The evening and sunset clouds were beautiful. We saw sea stars and bioluminence. The sparkles in the water was magical. Nylon body suits were provided as protection from jelly fish we couldn't see in the dark. Snorkle gear was provided as well. My mask and hands just shimmered in the lights. This is perhaps a once in a lifetime experience for us, unless we travel back to Grand Caymam, because I would do it again.

Amazing experience! - This was such an amazing experience! The boat ride itself was enjoyable soaking in the great weather while music played. Holding the starfish was unique, and there were so many to see. The bioluminescent snorkeling/swim was so cool! I wasn’t sure what to expect, but it didn’t disappoint, with the blue glow of the water around us when we moved, and without movement, the water had a glitter effect when looking through the swim mask. Staff were awesome as well. Highly recommend!

We went to starfish... - We went to starfish island first- perfect temperature. Loved it. Our guides then took us to the bio bay. Good advice to swim under the boat- it was the darkest and best place to see it. Mosquitos were out-thank god our guides brought the bug spray. Loved our adventure. Thanks Aaron! We were allowed to bring our own drinks and snacks too. Kristin and Brian from Atlanta

Coolest thing Ever!! - This is one of the coolest things I’ve ever done. The picture and video don’t do it justice. To see the tiny plankton light up as you move past them. I highly recommend using a snorkel mast so you can see what’s happening around you. Slowly moving your hands in front of you looks like you are shooting electricity out your finger tips. Our crew was great- very friendly, very knowledgeable, and happy to shoot pictures and video for us. This boat has a double hull, so we could swim under it for extra darkness to see the glow even better. Would highly recommend this excursion and this crew.
