⭐⭐⭐⭐⭐ We had such an amazing experience on our bioluminescent bay tour! The crew was absolutely wonderful and did a great job working around the weather to make sure we were still able to get our tour in. They were friendly, accommodating, and made the whole experience so much fun. Seeing the bioluminescence was incredible and definitely something we’ll never forget! Highly recommend! 💙✨
Seeing the sea stars was really neat, but the bioluminescent plankton takes the cake. The seemingly glittering water as your hands pass through is truly a wonderful experience. Our guides were fabulous and took great care of everyone.
The experience was so fun, I had no idea the there was plankton that lit up when brushed against.. they were like underwater lightning bugs.
This was a fun and smooth tour! The Captain was knowledgeable and personable. From pick-up to drop-off it was all stress free.
What a fabulous experience! Was a once in a lifetime experience swimming and seeing the bioluminescence Crew was excellent
Fantastic experience from start to finish. So much fun. Pepe and Jose were awesome. Would definitely recommend!!!
An incredible and totally recommended experience. The bioluminescence excursion was spectacular, something truly different and magical. Everything was very well organized and we enjoyed it a lot. Without a doubt, one of the best memories of our trip to the Cayman Islands!
The experience was amazing, something me and my family will always remember.
The most amazing life experience ever. The captain and crew hand were absolutely amazing, helpful, happy. Couldn’t have asked for more
The guides and crew members of Seafarers Adventures were very pleasant and helpful. The bioluminescence was amazing as was starfish point. I would go with this company again.
