Witness nature’s glow in Grand Cayman’s world-famous Bioluminescent Bay, where millions of microscopic plankton illuminate the water with every movement. This unforgettable evening boat tour invites you to swim among the stars—or simply enjoy the glowing display from the deck—as our expert local guides share the fascinating science and stories behind this rare natural phenomenon.
The adventure begins at Starfish Point, where you’ll have a chance to explore the calm, shallow waters and discover the curious upside-down jellyfish that call it home. Then, under the night sky, we head to Bio Bay for the main event—a glowing swim you’ll remember forever.
