Grand Cayman Bioluminescence Boat Tour and Starfish Point

About this activity

Some evenings in Grand Cayman end with the sunset. This one is only getting started.

Cruise across North Sound as the Caribbean sky changes color, arriving at peaceful Starfish Point to observe colorful sea stars beneath the warm, shallow water. Then continue into the darkness toward Cayman Kai’s secluded Bioluminescent Bay.

Grand Cayman is one of the world’s most remarkable destinations for witnessing this rare natural phenomenon. Watch millions of microscopic organisms illuminate the water from the boat or enter for an optional swim as blue-green flashes shimmer around every movement. Along the way, knowledgeable local guides reveal the science behind the glow and the fragile ecosystem that makes it possible.

From pickup along Seven Mile Beach to the final cruise beneath the stars, the entire evening flows effortlessly. This is an unforgettable journey from Caribbean sunset to glowing water.
