5.00The weather did not provide during our visit. Tim reached out by lunch to let us know the wind and waves wouldn’t be safe so the trip was cancelled. Rescheduled to the next day but the weather didn’t improve much so it was cancelled for a refund. I know most reviews are typically about the experience but I wanted to share how positive I am about the operators. I will be rescheduling this experience/excursion on my next visit because I trust these guys to provide a safe and respectful tour. Thanks again!

5.00We had a little time at starfish point to watch the sunset and see some starfish. Then headed to a cove and got the unique experience with the bioluminescent organisms. Make sure you have someone who will take some videos and pictures from the boat. Very unique. Also enjoyed the stars on the ride back to the marina.
Cool family experience

5.00Lovely trip. This was an easy and relaxing adventure. The pacing was perfect, we felt safe and enjoyed the moment. Our family of three enjoyed visiting with the other passengers on this trip and appreciated the hospitality of the crew. There was very low pressure, lots of support, and we felt completely at ease with the whole event.
This was a fun experience...

4.00This tour was nice but would have been more fun and festive had they served drinks and snacks, as most tours do. The starfish beach was pleasant but only saw 4 starfish. Crew and boat were very nice.
