The Luminous Lagoon extends through the marshlands of Trelawny, stretching from the small community of Rock to the historic town of Falmouth. In the 18th century, Falmouth held great significance as one of Jamaica’s pivotal ports, situated at the confluence of the Martha Brae River and the Caribbean Sea. Serving as a vital trade hub, the lagoon’s wharf facilitated the transfer of goods from large English vessels to smaller ships for transport inland. Today, the lagoon’s geographical location holds scientific importance as the ideal site for observing and studying dinoflagellates, remarkable microorganisms that illuminate the water’s surface where salt and fresh water merge, creating a captivating glow in the warm, shallow depths.
