Grand Cayman Bioluminescent Bay and Starfish Point Tour

Grand Cayman is one of the world’s most remarkable places to experience bioluminescence, a rare natural phenomenon that turns the water into a display of light after dark. Experience two sides of the island in one evening — from the shallow waters of Starfish Point to the glowing waters of Bioluminescent Bay.

Begin at Starfish Point, where you can wade through warm Caribbean water and see colorful cushion sea stars in their natural environment, along with unusual marine life such as upside-down jellyfish.

Then continue by boat to Bio Bay. Millions of microscopic organisms illuminate the water with flashes of light as it moves, a natural phenomenon found in only a handful of places around the world.

Watch the bioluminescence from the boat, or slip into the water yourself and see the glow respond to every movement around you.

After an evening on the water, settle in for the boat ride back with memories of the Caribbean and a bay that glows after dark.
