"Down D Islands" (DDI) refers to a popular Trinidadian boating, "liming" (socializing), and swimming experience around the small islands off the northwestern coast of Trinidad. Located near the Chaguaramas Peninsula, this favorite local pastime involves chartering boats to visit picturesque islands like Monos, Chacachacare, and Gaspar Grande for a relaxing day of water sports, lounging, and stunning ocean views
