Black Coral I & II

The two Black Coral moorings bracket a stretch of outer wall where the park's namesake colonies still grow in thickets: bushy, iridescent, and increasingly rare elsewhere in the Caribbean after centuries of jewelry harvesting. Between the black coral fans the wall runs the full Jardines repertoire: tarpon stacked in the ledge shade like chrome beams, reef sharks tracking the group from the blue, hawksbills working the sponges. The deeper ledges reward a careful eye for big groupers backed into ambush spots. It is the archipelago's best pure wall diving, dived unhurried from the skiffs.

The moment you come for: Living black-coral thickets, tarpon under the ledges, sharks shadowing the wall.

Topography: The outer reef's edge, stepping over ledges and buttresses hung with black coral colonies.

Current: Along-wall set on some tides.

Entry: Paired moorings along the outer drop; dived as two variations on one wall.

Hazards: Depth along the ledge line; standard shark protocol applies.

Permits & rules: Access only through the park's licensed operation.

Conservation: Black coral is protected and slow-growing; buoyancy errors here damage exactly what the site is named for.

Nitrox: Worth it here: profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
