“Stunning experience, and Mark was a kind and knowledgeable captain! The ability to view the bioluminescence is based on how bright (or rather, how dim) the moonlight is. Before booking, I checked the lunar schedule and opted for a night as far from the full moon (as close to the new moon) as I could during our time in Grand Cayman. Definitely paid off, Highly recommend this experience!”
