Boat access, strong surge and a steep reef slope make this a confident-crew dive with seasonal black trevally action.
About Black Jack Hole
Black Jack Hole is a boat-access reef off Little Tobago where a steep slope, strong surge and current can funnel black trevally through the site in season. Sea fans, barrel sponges and a prominent brain-coral feature give the dive a big, textured feel, while tarpon, jacks, sharks and rays keep the water column busy. It is best for divers comfortable with quick descents, moving water and a briefing-driven team approach.
