Weather was overcast and...
Steven_C, October 2026
Weather was overcast and drizzle in the beginning and remained cloudy which maybe affected the bioluminescence but overall Pepe and his team made it fun. We laughed and were informed about certain informational pieces about the island. Overall great time and super super neat. Would definitely like to do this one again!!!! And if Pepe reads these reviews, the joke about Cuba was great!! Thank you!!!

An Experience of a Lifetime
GoneHiking2, October 2026
This is a once in a lifetime snorkeling experience in the Bioluminescent Bay.
The crew was awesome, friendly, caring and fun. They ensured that everyone was safe and prepared. We stopped to see the sea-stars (commonly called starfish) but they are not fish then on to the bioluminescent snorkel. The trip out we saw a beautiful sunset and on the return trip a lot of stars. I highly recommend this company. They are family owned and the oldest tour company in CI. Don’t miss this tour with them.

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! 💙✨

Magical experience
Kerri_S, September 2026
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.
