About Black Rock Reef
A shallow East End reef with sandy channels, rolling coral gardens, and freestanding coral heads linked by narrow passages. Black Rock Reef is a boat-accessed site with big fish schools, Caribbean reef squid, and ledges that shelter lobsters and eels, plus a giant barrel sponge that marks the ridge. A careful line through the mooring keeps the dive tidy and makes the shallow coral heads easy to work.
