Trinity Caves
Dive site
Trinity Caves is one of the most elaborate cavern systems accessible to recreational divers in the Caribbean — a honeycomb of three interconnected passages that tunnel through a coral head rising from 18 m to 6 m, with natural openings large enough that ambient light illuminates the interiors throughout. Silversides school inside the chambers in summer, packed so densely the passages appear filled with liquid silver. The outer walls of the structure support elkhorn and staghorn coral, and resident nurse sharks drape themselves across the sandy floor of the deepest cavern throughout the year. No cave certification required; cavern training is sufficient.
