Grand Cayman’s Bioluminescent Bay glows after dark as millions of microscopic plankton light up with every movement. The shared evening boat tour starts at Starfish Point, where you can explore calm, shallow waters and look for upside-down jellyfish before continuing to Bio Bay under the night sky. Local guides explain the science behind the glow during a guided swim, while the boat deck provides a dry viewing option. Round-trip transportation from Seven Mile Beach hotels is available, and the bay’s natural intensity varies each night, so the display can look different from one visit to the next.
