The Luminous Lagoon stretches along the marshlands of Trelawny from the small community of Rock to the town of Falmouth. In the 18th century when sugar was king, Falmouth was one of Jamaica's most pivotal ports. Experience this mystical phenomenon! At night, the lagoon sparkles and glistens when disturbed, as these microscopic organisms produce an eerie glow, reflecting the outlines of fish and other objects in the water. The luminous lagoon is said to be the largest and most brilliant of four in the world, a fact that continually attracts and awes visitors and scientists from around the world.
