Turks & Caicos, Caribbean

Grace Bay's 12-mile arc of powder-white sand and astonishingly clear water—with seafloor visibility up to 30 meters—defines Caribbean perfection, attracting 1.6 million visitors annually. The fringing reef hosts 250 fish species, supporting year-round diving that ranks among the top Atlantic destinations, with average visibility outperforming #5 by 10 meters. With average water temperatures of 27°C, it is warmer than the typical Caribbean rival by 2°C, ensuring comfortable swimming year-round. Unlike #6 Railay Beach's boat-only access, Turks & Caicos offers direct flights from 16 US cities, yet retains quiet elegance with only 3,000 hotel rooms along the entire shore, keeping 40% of the coastline undeveloped. Average underwater visibility exceeds 25 meters on calm days.
