5.00George’s Watersports gave us one of the most unforgettable experiences we’ve ever had as a family. From the start, everything felt organized, welcoming, and most importantly—safe. Traveling with kids, that matters a lot, and their crew went above and beyond to make sure we were comfortable every step of the way. The highlight was the bioluminescence tour—and instead of kayaking, we actually got in the water and swam… which made it even more incredible. The moment you move in the water, it lights up around you in this glowing, electric blue—it’s hard to even describe how surreal it feels. Every kick, every splash, even just waving your hands creates this magical shimmer all around your body. It honestly felt like swimming in stars. Seeing the kids’ reactions made it even better—it’s one of those rare experiences where everyone is just in awe at the same time. What really stood out was how safe and well-managed everything was, even while swimming at night. The team stayed close, gave clear guidance, and made sure everyone felt confident in the water. That allowed us to fully relax and just enjoy the moment as a family. If you’re heading to the Cayman Islands, this is a must-do. Swimming in the bioluminescence is something you truly have to experience to believe—it’s magical, unforgettable, and something our family will be talking about for years. 🌊✨

4.00The bioluminescent plankton were so faint I couldn't even get them to show up on my camera, but at least there was a nice boat ride
Great experience!

5.00Definitely a once-in-a-lifetime experience! We went on the night with the smallest sliver of moon for the brightest phytoplankton. It was magical as I waved my hands around in the water--just like a Disney fairy godmother waving her wand. The water in the shallow bay was warmer than the open ocean, which I appreciated. The guides provided thin wetsuits to help protect from the tiny jellyfish that live at the bottom on the slim chance that they'd float up (I wasn't worried). The tour was organized and well-executed. Thank you!
Family friendly, great boat/equipment!

5.00Great all around excursion. Staff - Friendly, knowledge and helpful. We have a 6 year old and they had age appropriate gear and support for them to snorkel. Experience - the plankton lived up to the hype. It was very bright when you swam around in it. And as they say, it’s 10x better with you face in the water vs viewing from the boat.
Very good, interesting and unique.

5.00Really cool to see how bright the water gets when you move in the water. The tour operator was great - liked their idea of using pool noodles to hold us up so we didn’t disturb the jellyfish. This is something everyone should try while on island.
