The story

Where the cold water meets.

Petty (Pos III) sits at Menjangan's southeastern corner, where two currents meet. The wall starts at 12m and falls past 40m. Sea fans the size of doors, soft coral coverage, and the occasional cold upwelling that pulls in the unexpected.

Turtle sightings are common. White-tip and black-tip sharks pass through. Barracuda schools hold in the current. And once or twice a season, a mola-mola wanders up from the deep.

"Watch the blue. That's where everything good shows up."

Titan triggerfish are territorial here in nesting season — give them space. Otherwise this is one of Menjangan's most rewarding dives for big-fish chance.

Topography

How the dive unfolds.

Wall dive. Descend to your comfort depth (25m for most), drift along the face with the current, ascend back along the wall.

Plan a typical 50–60 min dive: drop in, descend to 25m gorgonian zone, drift the wall, ascend slowly. Watch the blue for pelagics. Mind triggerfish nests in season.
