Twin Ledges

Twin Ledges lies just inside the inner reef tract, which runs parallel to the shore. This reef tract is marked by two buoy lines: one to the north (Oakland Ridges) and one to the south (The Caves/Twin Ledges). The Twin Ledges site, described in this chapter, is situated between these two buoy lines and slightly closer to the shore. At this site, there is no permanent mooring buoy. Dive and snorkel tour operators typically drop anchor in the sand to the east of the reef, positioning the boat over the central sand channel. Visibility varies but is generally sufficient for a clear view of the reef from the surface. Currents are usually mild. The natural reef itself varies in depth from 10 to 20 feet (3 to 6 meters). Comprising a long, relatively narrow stretch of limestone blocks, the reef features undercut areas. The most intriguing part for divers—and snorkelers skilled at breath-holding and duck diving—is a sand channel that runs approximately 17 feet (5 meters) wide through the blocks, extending from north to south for about 80 feet (25 meters). Smaller channels branch off from the main sand channel, cutting through the blocks and leading to the sandy seabed on the eastern side. Toward the southwest and northwest, the reef flattens out and is adorned with sea fans and other soft corals. Directly westward, as you approach the shore, the reef transitions into sandy terrain. Divers and snorkelers exploring Twin Ledges are likely to encounter a diverse array of fish and crustaceans. Bermuda chub, Atlantic spadefish, bar jacks, and sergeant majors often surround snorkelers near the surface. Meanwhile, balloonfish, angelfish, parrotfish, grunts, goatfish, trumpetfish, and occasional scorpionfish inhabit the reef or the sand channel. Beneath the limestone blocks, nurse sharks, lobsters, glassy sweepers, and grouper find shelter.
