Dindini Wall
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
When the sea allows the run outside Chole Bay, Dindini is the reward: an ocean-facing wall where visibility jumps, the coral grows in unbroken terraces, and the fish come bigger. Hawksbill turtles work the sponges along the lip, eagle rays and barracuda pass in the blue, sweetlips and grouper hold the undercuts, and the wall's crevices hide morays and lobster. There is a satisfying emptiness to it — no other boats most days, just the reef bending out of sight in both directions. Conditions gate access; in the calm October-to-February window it becomes a regular fixture.
The moment you come for: Clear-water outer wall; turtles on the lip and rays in the blue
Topography: Outer-reef wall and terraces dropping into clear oceanic water
Current: Outside the bay on the open coast; swell and along-reef current decide the day.
Know before you splash
Hazards: Swell, surge near the lip, and exposure on the open coast.
Permits & rules: Marine-park daily fee applies.
Conservation: Within the marine park's outer zone; the wall's undercut corals are fragile — no handholds.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
