We weren’t - We weren’t sure what to expect, but it turned out to be one of the best nights of our trip. Easy pickup from our hotel, cool breeze on the boat, and the glowing plankton were stunning. So worth the time and money.

Such - Such a relaxing and beautiful night tour. We stayed on the boat and just admired the glow—it was perfect for us. No need to swim to enjoy the view. The punch and water were a nice touch. Simple and lovely.

Swimming - Swimming in the glowing water was an unforgettable experience! It felt like being inside a scene from a movie. The crew provided snorkel gear and explained how it all works. So cool and unique. A must-do on the island!

Underwhelmed - To be clear, my wife and I did not go into the water because we do not swim. So others may have a better experience. First stop for the star fish was good. Boat staff was great! Informative, helpful - nothing bad to say about them. We had already been there before - so nothing new for us. My beef - the bioluminescent bay is over rated. The pics make it look like you are walking on the beach near a glowing bay. Everything is glowing. Not the case. You drop into the water form the boat. In reality the glow is only from movement...paddling, kicking, etc. The pics are all enhanced. I think the experience would be fine if that is what is advertised....but it is advertised as way more than the reality.
