We booked a tour to the... - We booked a tour to the Bioluminescent bay. Mike and Sugar Bear were awesome. We didn't see as much in the bay as we wanted, however these 2 guys made us laugh and smile.

Great tour but could be a little better - The only way you see the bioluminescence and the plankton is by swimming with them. If you donโ€™t want to get in the water this tour is not for you. I had a fun time and enjoyed myself.

Great boat trip but not much bioluminescence - We went on this tour in January 2025. The staff on the boat were fun, friendly and informative! The boat was nice, clean, and comfortable! We saw very little bioluminescence and it wasnโ€™t like it was shown in the listing. Perhaps the jelly fish were not in that location when we went.

Expensive โ€œboat rideโ€ & HUGE disappointment! - We were HIGHLY disappointed after paying $270 for a โ€œboat ride.โ€ We thought we were going to cruise to see colored bioluminescence. We couldnโ€™t even photograph the saltwater-colored plankton. After more than 2 hrs on the boat, the demonstration lasted about 20 mins with someone splashing around in the water. The crew was super and the skipper was shocked when I showed him the website photo of what we THOUGHT we were going to see. BIG disappointment! He said he spoke with his supervisor (apparently by phone) and to expect a phone call, today. NO ONE ever called. DONโ€™T was your money!

Family was disappointed - The staff were fantastic and I think they even felt badly that the experience wasn't great. The starfish and jelly fish part of excursion took away too much time in the bay. Perhaps since it was the day of these tours the luminous part wasn't that great.
