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.

Itinerary

1Starfish Point
Begin your evening with pickup from participating accommodations in the Seven Mile Beach area. The boat generally departs Raleigh Quay at 6:30 PM during summer and 5:30 PM during winter, with hotel pickups scheduled earlier. After leaving Raleigh Quay, stop at Kaibo Dock, the alternative meeting point for guests staying outside the Seven Mile Beach area. From there, continue by boat to Starfish Point. Step into the warm, shallow Caribbean water and look for colorful cushion sea stars and seashells resting along the sandy bottom. Your guides will introduce you to the marine life found here, including the unusual upside-down jellyfish. Enjoy time in the water and the peaceful surroundings before boarding the boat again. Then continue toward Cayman’s Bioluminescent Bay. Once darkness settles in, the lower light conditions allow the bay’s natural glow to become visible, setting the stage for the highlight of your evening.

2Bioluminescent Bay
Once darkness settles in, arrive at the Bioluminescent Bay near Cayman Kai, where millions of microscopic organisms create flashes of light as the water moves. Spend most of your boat tour here while your guides explain what causes the bioluminescence and why this particular bay provides the conditions for the phenomenon to occur. Watch the glow appear around the boat as the water is disturbed, creating a completely different view of Grand Cayman after dark. You can enjoy the bioluminescence from the boat or choose to swim in the bay, where movement through the water makes the glow visible around you. Swimming is optional. After your time at Bio Bay, return by boat via Kaibo Dock and Raleigh Quay Private Dock. Guests using the shuttle service will then be transported back to participating accommodations in the Seven Mile Beach area. Total duration: approximately 3 hours, including transportation. The boat tour itself lasts approximately 2 hours.
1 hour 45 minutes • Admission ticket free
