Grand Cayman Bioluminescence and Starfish Point

About this activity

One unforgettable evening. Two of Grand Cayman’s most extraordinary natural experiences.

Begin at Starfish Point as the Caribbean sky changes color above warm, shallow water. Observe colorful sea stars in their natural habitat while your guide shares fascinating insights into the marine life and delicate coastal ecosystem surrounding you.

Then cruise into the night toward Grand Cayman’s secluded Bioluminescent Bay—one of the world’s most spectacular settings for witnessing this rare natural phenomenon. Watch millions of microscopic organisms illuminate the water from the boat or enter for an optional swim as flashes of blue-green light shimmer with every movement.

With transportation from selected Seven Mile Beach accommodations, a certified captain and crew, snorkel and mask, life vest, water, and fruit punch included, everything is arranged for an extraordinary evening beneath the Cayman sunset and stars.
