Whistling Cay

Whistling Cay sits at the eastern end of St. John, in the waters of the passage between the US and British Virgin Islands, and the name captures perfectly the character of this windward-positioned cay — wind moving through the vegetation and rock formations creates the whistling sounds that gave the island its name and that still greet visitors at the surface before the dive begins. The underwater environment at Whistling Cay benefits from this eastern exposure in the way that all current-influenced sites benefit from the ocean's food delivery: fish densities and invertebrate communities that are richer than the more sheltered western sites. The dive at Whistling Cay follows the cay's rocky base in water that is clearer and bluer than the more enclosed Virgin Islands bays, the influence of the open Atlantic passage making itself felt in the exceptional visibility that is one of the site's most immediately striking features. On calm days — and the conditions need to be appropriate for this site to be safely dived — visibility can reach 35 metres or more, giving the whole dive a spacious, luminous quality that the more sheltered sites cannot match. Fish life around Whistling Cay leans toward the more pelagic species that characterise the open-passage environment. Large schools of horse-eye jacks and bigeye scad move through the channel area, hunting in formations that are coordinated by a communication system visible in the synchronised movements of hundreds of individuals. Caribbean reef sharks are regular presences, their patrol routes taking them around the cay base in the unhurried circuits of animals that have established this territory as their own. Occasional larger pelagic visitors — bar jack in dense schools, the flash of a rainbow runner — pass through the passage and contribute to the sense of a site that is connected to the open Atlantic. For beginner divers visiting on the calmer days when conditions permit, Whistling Cay provides an experience that expands the horizon of what Virgin Islands diving can include. The eastern exposure creates a site with more character and variability than the sheltered bay sites — a natural next step for divers who have consolidated their skills in calmer water and are ready for the more dynamic environment that makes open-passage Caribbean diving so compelling.
