Said to be the world’s most popular dive site, Molasses Reef is kept clear by the Gulf Stream off the Atlantic coast of Key Largo. Populated with a very high concentration of animals and corals (especially star & Elkhorn coral), the reef’s inhabitants are a good representation of life throughout the Keys. Look for vase sponges and the sea turtles that flock to them. Many coral formations are shallow enough to make great diving for novices, and spots drop to about 50 feet for the more seasoned explorers. The site got its name from a cargo ship that ran aground while transporting barrels of molasses, but divers can only see the remains of the Windlass wreck, also known as the Winch, around mooring buoy 8.
