    StandoutExceptional marine biodiversity

    Long Rock, off Little Corn Island, is where we head when we want a proper Caribbean drift. It’s not the deepest site, topping out at 21m, but that 100m long, 6m wide reef structure on the west side really pulls in the fish. We usually drop in and let the current carry us, watching for the big schools of fusiliers and snapper that congregate here, sometimes so thick they block the light. The reef itself is a tapestry of Boulder Brain Coral and massive Lettuce Coral, punctuated by the occasional Elkhorn. Look closely among the coral heads for Coney and Chalk Bass, and keep an eye out in the blue for the patrolling barracuda. The Angelfish, particularly the Midnight and Blue Parrotfish, are practically residents. Visibility averages a comfortable 19m, but a calm day can push it to 25m, making the drift even more enjoyable. This is a site for Open Water divers comfortable with a bit of a ride, offering a classic Caribbean reef experience with consistent action.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
