Rum Cay’s location on the continental shelf presents opportunities for some of the best diving in the region, both inshore and on the edge. Sites include drop-offs, deep reefs, numerous tunnels big enough to drive a vehicle through, and the wreck of the HMS Conqueror (1855) preserved as the Underwater Museum of The Bahamas. Spectacular diving can also be found at huge walls such as the 60-foot coral walls at the "Grand Canyon," that almost reach the surface of the water; "Chimney,” where you enter the coral reef through a natural hole that looks like a hearth, and then a tunnel goes up through the reef; and “Pinder’s Point,” a deep wall with Staghorn coral not far from Port Nelson.
