This lagoon, surrounded by mangroves, is home to microscopic organisms that emit phosphorescent light when the water is agitated. Plan your trip for dusk and then take a boat ride onto the lagoon. As the water is disturbed, you'll see an eerie light illuminating the waters below. Wave your hands or drag a stick in the water to make the water glow in the dark. Those who wish can swim in the luminous waters as well. (The lagoon is about 4-5 feet deep at the center.) Boats leave from the Glistening Waters Marina, where there is also a restaurant and nightclub. Visitors can enjoy dinner at the Glistening Waters restaurant while watching the bioluminescent show on the water.
